@parkourse No, seriously, more critically? People have always perceived straight relationships as something more serious and important, so straight relationships have always received more criticism. Which, of course, is pretty homophobic. To do this, it is enough to compare what rating straight smut and yuri smut have on the mangadex, especially the violent part. For example, girl versus girl sexual attacks will always be perceived as something fun and hot, while boy versus girl will always receive treatment as sexual harassment and humiliation of a female character without any "buts".
People just use the attitude "straight relationships are real, lesbian relationships are cool and fan service", Of course, with the exception of weirdos, which even lesbian near-hentai will perceive as a wholesome love story.
@BalrogDeMorgoth This is true, but people still have such a secret weapon as "interpretation". For example, one dude on reddit "identified" the feelings between them based on the interpretation of their facial reactions.
@MelReinH The problem is not that she is gay, but that a straight character, especially a male one, in her place would obviously be completely hated for similar behavior if it were not originally portrayed as a negative character. I can even predict how ANN will call him incel or something. But she's a lesbian, is hot and funny, so Gyari may not receive any punishment for that, that will literally killing a male character's "career".
