The simple meaning of feminism is this:
Support women's rights, and support other women.
Meaning, you have to accept white women, black women, asian women, native women, skinny women, fat women, short women, tall women, women who have s*x, women who don't, trans women, lesbian women, straight women, able women, disabled women, etc. Of course there will be women you encounter throughout your life that you dislike, but you should not be rude to a 'certain kind' of a woman. Meaning, hating 's1uts' because they have s*x a lot, or hating white girls because they're annoying you, is not feminism. Have a good day.
