I admit my vision on sexuality is currently very negative thanks for some people (rant)
In the past I joined a community out of curiosity and tbh to troll a bit. Since I saw them as flawed, they were incels that believes that women were attracted to women more than men.
Being on an incel community modified my whole vision of sexuality to be the worst possible, specially of straight men. Now I have disgust for people with sexuality itself, I hate to notice how much their sexuality affects their preferences and behaviors, in such many ways, I could have endless examples, and unfortunately I can't mention them without having risk, but I will mention some words as guidance: s3x as a need, male gaze on all type of media, fake romanticism, simps, using how rare is your sexuality as advantage, manipulation, disparity, etc.
And some of the things weren't all incorrect, it opened my eyes to see how common some of these things really are.
Other than that, the only thing they did is to help me discover I'm AroAce because they make me reflect that I never craved women (or men) like they do (or in any way at all). That is partly because I have a extreme disgust and fear to be mystaken as straight.
Changing a bit of topic, about their main points.
They weren't all gross things, they haved some points, society shouldn't treat heterosexuality as the main sexuality, and men should stop bothering women so much by aproaching them, as creeps.
And others a bit mystaken, like that women are bisexual leaning lesbians, that is stupid, and that all people are visually attracted to women, that is an excuse to evade saying male gaze.
That is why I intially stayed, the community was respectful and not very sexist, at first.
