You might be (behaving like) a SJW if you attempt to win a debate by calling your opponent a "hater" for disagreeing with you, and redirecting the conversation to be about you, and your own efforts and battle scars, so as to appear morally superior, and attempt to create the impression that the person who is opposing you has personally attacked you, when they have done nothing of the sort.
Well, not that I disagree with you that it's wrong to demonize people who disagree with oneself, but let's put it this way: if someone makes uninformed statements about, say, rape and the motivations for it, and then someone comes along and says, "You know, I have worked with rape survivors and have experience, and I think X and Y because Z," I think that's merely being factual or at least rational about stating one's opinions. I know that some people would love to claim that this is an instance of "redirecting the conversation to be about the person, their own efforts, and their battle scars so as to appear morally superior," but that doesn't detract from the validity of the person's experiences.
Furthermore, when someone tells another person that they are too emotional to have a rational opinion on any given subject because they were subjected to a specific kind of assault or violence, yes, that is personally attacking them. That it is opposition doesn't preclude its being a personal attack.
I understand why so many people are so quick to dismiss the experiences of others and call them "SJWs" to make light of their opinions, though. After all, bigotry and misunderstanding thrive on casual dismissal of facts and experiences. I see this in my everyday life, where bigots of different stripes justify themselves by dismissing opposition as being "fickle" or "whimsical," among other things. To them, anything that points out bigotry and calls it out by its name is "too emotional" or "self-righteous." Religious bigots do it. Non-religious bigots do it. Atheist bigots do it. It is the same pattern of thinking across the board; it just goes by different labels and disguises itself differently for different contexts.
I'm just waiting for someone to casually dismiss this post for whatever reason or call me a "SJW." Watch this: Someone, most likely someone who denies that any given kind of discrimination or bigotry exists, will probably come along and find a reason to brush this post under the rug in an offhand manner. I don't mind, though; after all, some of these people have dismissed feminists as "professional victims," for example. I guess one shouldn't expect standards to be high when the threshold is in the gutter.
Edit: For clarification, my post is not directed at you, 4C, but at the behavior of certain people in some threads. I don't think you maliciously intended your post, so my criticism is directed at other posts of a certain kind.
