Like a lot of terms, "SJW" has largely lost whatever little meaning it had; people of all leanings, detractors, antagonists, supporters, all have lost sense of what it means so it has no weight left to it. If people use it in a sentence, it is largely indicative of a very reductive demeanour and an eagerness to reduce complexity to be more digestible to their worldview, as the human mind is eager to simplify things.
