"Egalitarianism is a trend of thought that favors equality among living entities. Egalitarian doctrines maintain that all humans are equal in fundamental worth or social status." This is me.
"Feminism is a collection of movements aimed at defining, establishing, and defending equal political, economic, and social rights for women." This is not me.
The reason that I make the distinction is that Feminism is SOLELY about equality for women. Whilst it's a noble cause that is not the only thing I care about.
Someone can tell me I'm a feminist all they like. I'm not. It might be part of my ethos but that title certainly doesn't define my entire moral compass. My focus isn't that narrow.
I agree that I want equality for women. Just as I want equality for everyone, regardless of gender, age, sexual orientation or any other variable you want to throw in there. Women don't take precedence just because they've been oppressed in the past (and still are at times, I'm not naive). Many people have been oppressed for many reasons. Focusing on one group as more deserving of equality activism seems like saying that they're more deserving of equal rights than anyone else that's been oppressed.
Everyone is deserving of those rights, not just the group with the loudest voices or the most backing.
