It’s not an assumption. It is a conclusion we have made off of personal experience with “feminists”. Online feminism can be defined as whatever it wants to be but from personal experience feminist are all men haters. An article could say lemons are sweet but if you take a bite of one you will see otherwise. Are you gonna trust the article or personal experience?
Honestly, I don’t know how it would come up in a way that doesn’t lead to further clarification anyway, and I would know if she hates men or not based on how we interact and if she says misandric things. If anyone, man or woman, tells me “I’m a feminist” and leaves it there, I’m going to be more confused why they said that without a follow up than anything else.
I would proceed to fact check the article, because that's not how you properly educate yourself about something. If you read one article and don't do follow up research and believe it wholeheartedly then that's a lack of critical thinking and research skills. Besides, things like taste are subjective. Yes, lemons are widely considered to be sour, but there r probably some people out there who might consider them sweet, due to their personal experiences.
i'm sorry you've had bad personal experiences with feminists but those weren't feminists. they were radicalist. just like how incels are a small minority of men who are involuntarily celibate that hate women. i would be wrong to make the assumption that all men who happen to be involuntarily celibate also hates women.
So you are a feminist then? You can't say you will continue to support a movement and then say you won't support a movement. It's not an organization. You're making such vauge assumptions about modern feminism as whole which shows me that you are undereducated about it. Especially if you truly believe the radical feminist are the ones at the top. Are you like referring to someone specific who claims to be a feminist?
