Sometimes SJWism is needed, like with countries like Egypt that are completely crap and have the same homophobism, racism, and sexism SJWs complain about.
There's nothing crazy about calling out broken laws in countries with them. Someone speaking reasonably about say, Saudi Arabia or Iran is definitely doing the right thing.
But trying to make issues out of non issues in countries with decent rights for everyone is just pointless and infuriating.
If I hear SJW lectures I will tell them countries like Egypt, Afghanistan, Somalia, Pakistan, and the others have far worse social issues with these kind of things that make life a living hell for the people there.
