The funny thing is when I'm often talking to SJWs, they are often unbelievably uninformed. Despite saying they are for feminism and social justice, they have never actually sat down and read up on the definitions of political terms, or researched the first or second wave feminist groups that campaigned and protested. Not even a casual browsing of a wikipedia article.That's why these words are essentially meaningless when talking about politics, and why it's so hard to come to common terms in discussions which leads to misunderstandings and talking past each other. We need a different scale/spectrum, with more solid terms that leave less room for confusion.
They basically have read a few buzzfeed articles and use that as their talking points. Throw in some tumblr memes about powerful women in history with a short blurb. Each one just has their own personal interpretation of what they think social justice means. They've never actually sat down and thought about it.
I suppose it's understandable considering the school system doesn't really encourage critical thought or examining things, it's designed around memorization and parroting. And when they get out of school/college the teachers and professors are replaced by their news feed, as their information authority.
