Chris Pratt and Jennifer Lawrence have been making the rounds on their press tour for the upcoming film Passengers, and in their latest appearance on BBC Radio 1, what was meant to be a light-hearted segment ended on a disappointing note.

The two stars engaged in a game of "Playground Insults," in which they sit facing each other while relentlessly making fun one another and trying not to laugh. The person who can't keep it together, loses — and to be honest, half the fun is just watching them trying to stifle their giggles. (They only barely succeed.)

Things started out innocent enough: "Why did they call it Joy?" asked Chris. "'I loved you in Everwood' said no one ever," retorted Jennifer.

But it only escalated from there. Chris offered, "I recently told you that you act like Adele sings. I hate Adele."

"Where do you keep your Oscar?" Jennifer fired back.

It started off fine, but at the end of the segment, Chris makes a joke about Jennifer having a penis. It's important to note that we should never censor comedy, because humor is meant to be a diffuser of painful situations — where there is trauma or hardship, laughing about it can help many people heal.

But before you say, "it's just a joke," remember that the premise of this segment wasn't to make jokes, it was to be insulting. The truth is it's not insulting to imply that a woman has a penis. Gender identity has nothing to do with what kind of genitalia someone has. Biological sex does not determine gender, just like gender doesn't determine your sexuality. But even though these words are not inherently insulting, we live during a time where people aren't allowed to use the bathroom they feel comfortable because of their perceived body parts.

We are sure Chris Pratt did not mean to insult anyone, but his thoughtless insult is a reality for many discriminated against Americans. At the end of the day, even though body parts are not insulting, people still try to make them insulting. Right now, 80% of transgender students report feeling unsafe in school.

In an effort to show how these kinds of insults affect transgender kids, 14-year-old Corey explained in a viral video what it's like to be a trans girl at school. She was shunned by girls and teased by boys, and even laughed at by adults later on.

“I felt so stupid. Like a freak,” Corey’s notes say. “Like a misfit.”

Eventually, the bullying got so bad that her parents pulled her out of public school and opted to home school her instead.

The video, which you can watch here, has a happy ending thanks to Jazz Jennings. But the point is, Chris Pratt's school yard insult represents a real life experience for transgender kids all over the country. We hope Chris Pratt educates himself more on the issue, so he can help inform others about a completely unacceptable reality.
