You never hear the phrase “forced straight scene”.

Oh, you do. Not using those same words, but people have been complaining about random sex scenes since forever.

Straight people don’t need a plot reason to be onscreen

They do - if I have to know whether they're into noodles or lasagnas, there better be a good reason for that.

in your worldview gay people have to justify their existence each and every time

Wtf? Is projecting homophobia onto people your hobby or something? Fuck your strawman. If fallacies is your way to communicate, this is my last message to you.

I feel so triggered, because every time someone even offers the opinion of "do we really need so much unnecessary gay scenes in everything," people like you come and go "akchually you're just a bigot because you don't like bad cinematic devices that are just virtue signalling."

Anyway, changed my mind, this is my last message to you anyway, no need to have people like you in my life.
