How is it any of those things? By simply existing? This is all stuff people are applying to the trailer in their own headspace. It's a catch 22 because any situation where a gay character appears is going to be perceived as a "political statement", so the only way around it is to have no gay characters or extremely vague, hiding the fact gay characters where it's only said but never shown.
There has been plenty of gay characters in the history of videogames and nobody cared, because back then it wasn't an obvious political propaganda being shoved down people's throats like it is now.
