In place of SJW, I use the word overly woke, but the two mean the same. It's someone who overly relies on dichotomies of straight vs gay, white vs poc, or woman vs man in seeing and advocating for remedies of society. I don't mind someone saying "let's include more black figures into our curriculum" but someone who says "let's arrange mass protests outside of all history of western civilization classes and disturb teaching" or "let's protest cafeteria selections because of cultural appropriation" (which I don't view as a harmful thing)
The fundamental thing here is that I disagree with someone who I view as overly woke about how society should be. I'm for racial equality and some are for overdoing that philosophy at the expense of everything else and are pushing for a culture where the person who's offended most is always right. So, if you don't like the term, the fundamental thing is that you don't like that I have different viewpoints than you do, and that's actually what debate is. Sure it should be respectful too.
