The message seems harmless: “All Are Welcome.”

But what exactly does “all” mean?

That’s the question being asked in the small Massachusetts town of Groton, where residents submitted a petition on Monday night to discuss whether to remove eight new road markers that bear the aforementioned phrase.

Some feel that the word “all” implies that anyone — even criminals and terrorists — are welcome, while others think the signs are a direct shot at President Trump and his strong stance on immigration.

“That harmless little word is what we’re talking about,” Selectman Jack Petropoulos told the Boston Globe after the marker petition was filed Monday at Groton’s fall Town Meeting.

A group of residents signed the document and submitted it back in August, saying local officials didn’t get enough input from them when they were planning to put the signs in.

They asked that the message on the markers be changed to simply say, “Welcome” or “Welcome to Groton.”

On Monday night, the town voted by an “overwhelming” margin to keep the signs as they are.

The kooky crusade was spearheaded by 67-year-old Jack Saball, a former Groton selectman and retired police captain. He ultimately believes that the markers, which are actually engraved rocks, could open the door for illegal immigrants.

“It might include Groton as a sanctuary city,” Saball said. “We do not want someone to read this and think this town has a political agenda.”

Saball argues that because the rocks sit on public property, they should be apolitical.

Many people have been taking to social media to voice their opinion over the markers, which sit in various areas across town. One is situated at the entrance of a Hindu house of worship.

Local officials insist, though, that their positioning is in no way politically motivated.

“This was not a sanctuary-city issue, it was not a political or religious sign,” explained Petropoulos. “It was a way of telling people as they come in and out of our town that it’s a welcoming place.”

While numerous locals are upset about the markers, social media users from around the country have been showing their support.

“Imagine being so racist you can’t even pretend to be ok with a rock that says ‘all’ on it,” tweeted one person.

“When did the words ‘All are welcome’ become controversial?” another asked. “That’s the ultimate American ideal, engraved on the Statue of Liberty.”
