It's a woman main character in the trailer. Some loud, annoying gamers have a problem with that. Also that she isn't super conventionally sexy, and is a representation of an average woman. And some people are calling her trans and not in a pro LGBT way.

Someone here made a comment about sweet baby inc, which is a company that works with game studios to help encourage diversity, which is apparently the end of the world for the people who call everything new "woke" unironically
