I honestly have to agree here. Of course real rape and sexual assault is bad and shouldn't be encouraged, but to completely shy away from silly fun on fictional characters will have averse effects of its own. If we act like these screenshots are some of the worst things, we are nurturing this culture where anything is terrible.
The other day in another community, I mentioned it's okay for a guy to tell a girl she looks good and invite her out. This was quickly labeled as assault and I was chewed out for that. This is the kind of culture we're going toward if we're being this sensitive even toward silly screenshots of fictional female characters.
It also reminds me a bit of a double standard, because I recall from E3 2017 that it was completely okay for girls to undress Link in BotW and exclaim how sexy he looks. ...Which I think is okay! But it should be equally okay for female characters
