: If feminism prevalent

Depends on which era/idealogy of feminism you are talking about.

if you mean the group of Tumblr feminists who "trigger" any time any one suggests anything that doesn't coincide with there world view then

that would be a detriment to the existence of society. As speech is generally a good thing.

Do you believe it exists?

yes because it does.

Why

Because it was once valid and rather important.

at least I am assuming that is what the first stream of words means.

Feminism is real and is not a bad thing but feminazis who are crazy and take it to far can drown

Feminism is an ideology,and every ideology exists to some degree every where in the world.Some places have it more than the others.

i don't know whether OP didn't have world history on his/her class or is purposely being misinformed.
