A political activist who uses his/her reputation for activism, organization, and political ideology for the purpose of hitting on people.
A man claiming to be a feminist, making grand declarations about sexism and how he’s not a sexist, and then uses this in order to sleep with as many women as possible while sexually commodifying those women is a mactivist.
I hate mactivist with a passion. It’s not their looks that even matter, they just drag you in with their knowledge in activism and ideas. I see so many every time I protest. That’s hella low.
