This is just how female brains work in general. They get mad or upset about imaginary or nonsensical shit constantly. The female brain is a hormonal mess of fantasies that always paint themselves as victims of whatever great transgression can justify their endless victimhood and pity party of that week.
They say they "see" men get angry about ugly bitches in videogames but what they actually mean is they saw posts online where men were talking about how sick they were of every beautiful female in one of their primary forms of entertainment has been hit with the ugly stick (to appeal to trannies, specifically, which you think would actually upset them) and this gets absorbed by the female brain and turned into this fictional (but real in their mind) scenario of men fuming and screaming and planning terrorism over not getting to see jiggly anime tits and ass in their latest game.
