A quartet of immigration activists and a gaggle of animal rights protesters disrupted a Republican presidential candidate forum organized by an evangelical Christian group on Friday night in Iowa, shouting about deportations and 'violence' toward fish and turkeys.

'I feel like this is being conducted in Berkeley, California,' moderator Frank Luntz quipped as police escorted one agitator out.

Others were met by chants of 'USA! USA!' from a crowd estimated at 1,500.

Minutes into the event, featuring seven GOP candidates gathered around a banquet table dressed in Thanksgiving colors, protesters who favor citizenship rights for illegal immigrants unfurled one banner in the front and another at the back of the hall.

Drake University student Phoebe Clark and Patrick Stall, representing an ad hoc group called 'Against Borders Everywhere,' shouted at the foot of the stage, 'We're not going to leave!'

The pair leaped over a barricade that separated the audience from the stage. Secret Service agents, on hand because onetime co-front-runner Dr. Ben Carson has a protective detail, were momentarily shaken but not stirred – and made no effort to stop them.

'WE'RE NOT GOING TO LEAVE!' Patrick Stall, left, and Phoebe Clark, right, yelled their support for illegal immigrants as seven Republican presidential candidates and moderator Frank Luntz went on with a public event – largely without skipping a beat. Also not batting an eye were Secret Service agents who let them hop a barricade to get near the stage

The others' banner read: 'Citizenship now.'

'T.R. McKenzie,' one of the men who was ejected wore a Marco Rubio campaign sticker as part of his effort to infiltrate the conservative gathering.

'Some homies and I were just thrown out of the Family Leader Forum with the Republican candidates,' he wrote on Facebook.

'F***ing [Donald] Trump didn't show so I couldn't take his head and collect my reward.'

REALLY? Animal rights protesters grabbed a moment's attention yelling this PETA slogan, as Republican candidates talked over them and moderator Frank Luntz shook his head silently

Stall insisted that Luntz put immigration issues front-and center: 'We want you to talk about immigration right now,' he demanded loudly.

Luntz, the famously unflappable focus-group expert, calmly put him on the spot.

'Everyone is going to have a chance to be heard,' he said, 'but we're going to do it with respect, with dignity and sincerity.'

'We will address it for 10 minutes if you will take the banner and sit down. Otherwise we will not address it at all.'

The pair didn't move. 'We're not going to leave!' Stall said.

Police ejected the duo from the Community Choice Credit Union Convention Center, to cheers.

'Everyone give a hand to our men and women in uniform,' Luntz deadpanned.

In the lobby of the convention center, Stall blamed Republicans for wanting 'to talk about their pro-family policies. And the fact is their policies are trying to deport Latino immigrants.'

'They're trying to break up families,' he told DailyMail.com.

Republicans in general have opposed a pair of executive orders from President Barack Obama whose effect has been a stand-down of federal deportation forces in millions of cases of illegal immigrants who were brought to the U.S. as children, and some of their parents.

Asked if he opposed enforcing federal law, Stall shot back: 'It's unjust. I don't care about the law.'

He added that his organization would continue 'talking about what's right.'

'F***ING TRUMP DIDN'T SHOW': One of the ejected immigration activists was upset that he didn't have the chance to confront Donald Trump

ANIMAL LIBERATION? A protester who complained about the consumption of Thanksgiving turkeys was tossed from the COmmunity Choice Credit Union Convention Center in Des Moines, Iowa on Nov. 20

CAMERA-READY: While Stall and Clark held one banner in front of the stage, two other activists stood in front of a waiting bank of cameras at the back of the auditorium

Stall's group staged an outdoor protest before the event, but it was sparsely attended amid a freak snowstorm.

Clark claimed immigration was 'being used as a distraction' in Republican politics.

'The real division isn't between citizens and immigrants. The real division here is between rich and poor,' she told DailyMail.com.

Asked if she and her fellow activists were also protesting against Democrats who aren't vocal about immigration policy, she said: 'Yes.'

'When?' DailyMail.com asked her.

'We haven't figured that out yet,' she answered.

Minutes later in the auditorium, four animal rights protesters staged brief solo interruptions, voicing complaints about non-vegan meals.

One woman shouted about 'exploitation' of turkeys.

A man yelled from the other side of the audience, as police dragged him out, that 'Fish is not food! It's violence! Animal rights now!'

One audience member shouted back at them: 'Go back to preschool!'

Animal rights activists generally believe that animals should be entitled to the same rights as humans – among them, the right to not be eaten as food.

A Des Moines police officer said none of the activists were arrested, but they were all escorted off the property as trespassers.

The eight people on stage – Luntz, plus seven candidates – largely continued talking as each protest played out, and offered little more than a few head-hakes.

'You watch the Democratic debates, and you don't see conservatives disrupting them,' Luntz told the crowd, attempting to enforce civility. 'You don't see conservatives being rude.'

'So if anyone else wants to get up and yell, do it now.'

Former Arkansas Gov. Mike Huckabee, one of the participating candidates, said on stage that the series of outbursts 'doesn't bother me, because I realize it's a reminder that we live in the greatest country on earth and we allow people to disagree with us.'

'Those people aren't going to spend the night in jail. They're not going to be shot on the sidewalk.'

And with a twinkle, he added: 'I know there are people here who wish they were.'

Joining Huckabee for the forum, organized by the influential 'Family Leader' organization, were retired surgeon Ben Carson, Texas Sen. Ted Cruz, former tech CEO Carly Fiorina, Kentucky Sen. Rand Paul, Florida Sen. Marco Rubio and former Pennsylvania Sen. Rick Santorum.
