Yes, many are racists or misogynists that only want white men represented. I don't, however, believe that most are that way. I think most just want to be colorblind again. Let me explain.
When I was growing up, Samus was one of my favorite characters. She wasn't a woman to me, she was just Samus. Same with every other character. Same goes for movies. Ripley wasn't a woman, she was Ripley. All I cared about was the character.
Even as recently as my undergrad years, I had a buddy I met in college I didn't even notice was of Asian descent until someone mentioned it months later. Perhaps that was because his name was Lawrence, but regardless. Race, gender, etc., were pretty insignificant to me.
Then I started browsing forums like GAF. Everything became about color, everything became about gender. And now I find myself noticing the race and gender of most characters. And I don't like noticing, because those surface-level characteristics are the most shallow elements of a character.
Now, I get that some of you may say, "It's good that you're noticing, because now we can fix the inequality." I get that, and I get the sentiment. But the bottom line is I don't like seeing race and gender first. I've been pushed into it by this huge focus on race and gender.
So to answer your question, OP: Why are so many people "anti-SJW"? Because they wish they could go back to being colorblind/genderblind. They want to go back to how they used to feel about characters. But they probably can't. Now that we've been so focused on representation as a society, we're all bound to notice. And that's uncomfortable, because many of us were raised on the notion that making race or gender an important factor is wrong.
