Which is pretty funny in a way.

I'm going off of the faq from the Feminism subreddit. I'll just focus on a few of their terms.

This seems like a fair definition of feminism.

Feminism is a collection of movements aimed at defining, establishing, and defending equal political, economic, and social rights for women. In addition, feminism seeks to establish equal opportunities for women in education and employment. A feminist is "an advocate or supporter of the rights and equality of women".

If someone supports the rights and equality of women they're a feminist.

Sexism is a pretty big thing for feminists.

Sexism is a set of beliefs claiming that real or alleged differences between women and men establish the superiority of men.

If you believe sexism is bad, that generalizing men and women is bad, you're probably a feminist.

Then there's good old misogyny.

Misogyny is the hatred or dislike of women or girls. According to feminist theory, misogyny can be manifested in numerous ways, including sexual discrimination, denigration of women, violence against women, and sexual objectification of women.

Which pretty much ends up being anything that attacks women or makes women look negative is deemed misogyny, most things that are deemed sexist are also deemed misogynistic.

If saying all women are Machiavellian is a misogynist statement to you, you're probably a feminist.

Slut shaming is a big feminist issue.

Slut-shaming is the act of making someone, usually a woman, feel guilty or inferior, for engaging in certain sexual behaviors that violate traditional gender expectations

If you're against slut shaming you're probably a feminist.

Rape culture of course is a big issue in the mind of a feminist.

Rape culture is a concept used to describe a culture in which rape and sexual violence are common and in which prevalent attitudes, norms, practices, and media normalize, excuse, tolerate, or even condone rape.

If you believe rape culture exists, you're probably a feminist.

Feminists would be bored without having the Patriarchy to yell about.

The general characteristic of the status of women under patriarchy is one of subjugation without legal status in their own right.

If you believe the patriarchy exists/existed in such a form where women were subjugated, you're probably a feminist.

None of this should really be much of a surprise!

Probably 99% of people that identify as blue or not red are greatly feminist. Most purple people are mixed with both feminist and anti-feminist beliefs.

Especially if you consider the other issues feminism claims for itself: homophobia, racism, transphobia, privilege, intersectionality, victim blaming, heteronormativity, sexual objectification, essentialism.
