She certainly wasn't going to keep quiet after an airline refused to let her gay friends and their two daughters use the Family Boarding facility.

AnnaLynne McCord took to social media on Friday to to post a scathing letter to Southwest for its 'hateful' behavior towards Jake Lapp and David Lionel and their little girls.

'Have you ever felt bullied?' the 31-year-old 90210 actress began. 'Have you ever been picked on? Have you ever been rejected? The one who got left out because for some reason to another person you didn’t measure up; you did not belong?'

Thumbs down: AnnaLynne McCord, seen at an anti-bullying event in Hollywood in July, has hit out at Southwest Airlines for refusing to allow her gay pals to board as a family with their little girls

'A couple of days ago, the young girls in this photo were made to feel just that by individuals who wear your logo and represent your company,' the former 90201 star wrote, referring to a photo of her friends and their kids that she included on Twitter.

'It was their first flight ever and they were so excited to join their Daddies on a family trip.

'Only your employees made it clear that these beautiful little girls and their fathers were not in fact "family." And when it came time for "Family Boarding" these little girls were shown what has caused the detriment in our world; hate.

'I ask you, why?': The 31-year-old actress took to social media on Friday to accuse the airline of 'bullying behavior towards Jake Lapp and David Lionel, seen on the flight with their daughters

Heartfelt: This is the full letter the actress also posted to her Instagram

'They were not allowed to board with the other families and had to watch as their fathers were told that they didn’t count as family. Love is what these wonderful little girls have for their Dads. Love does not separate, it unites,' the beautiful blonde Transporter 2 star continued.

'So, I would just like to ask you "why?"' she added. 'Why would your company representatives (the desk agents boarding the plane on behalf of your corporation) believe that it is okay to reject these little girls’ love for their fathers, making them feel that they are not good enough? That their family should be left out?

'Is that not a form of bullying? Is that not a form of hate? I certainly wouldn’t call it love.'

Scathing letter: 'Your employees made it clear that these beautiful little girls and their fathers were not in fact "family," ' she raged in her take down

'I implore you, as a company that seeks to provide a happy experience for all of its customers, to hire individuals who despise hate, not love; who embrace difference, not look down on it.'

And the Nip/Tuck actress ended her heartfelt letter: 'Please, don’t allow your company to promote the hate that destroys the pure innocence of the love of a child. With an Absolutely Broken Heart, AnnaLynne McCord.'

AnnaLynne has yet to receive a reply from Southwest, according to ET.
