Let's be honest, two girls kissing, I have never seen anyone have an issue with that as long as they also kissed boys. Also kiss is a euphenism here. Yes lesbians were seen as wgtow and somewhat persecuted but bi-curious hetero girls? Absolutely never seen that even hinted at. In fact a lot of pop culture put that on a pedestal. Because it's hot.
Unavailability to men, real or perceived without monastic levels of chastity is often where the persecution comes in. It tends to be directed towards lesbians, but bi women often face it once they are seen as not partaking in men’s fetishization of them
Are bi women not seen as available? I mean, are they bi sexual if they don't consider men as potential partners? It seems to me if they don't, then they're lesbians and yes I agree this is more stigmatized by the diseased culture.
