"f that term did not exist, many more SJWs would be doing it all the time without fear of being called out."
Doesn't this assume that if the term did not exist, the thing in itself which you rightly claim "they would be doing", still exists?
If they would be doing it in absence of the term, what would they be doing? the thing? what thing? the thing that we don't have a name for, but yet exists. It exists before the name, and in spite of the lack of a name. The world exists first. Then we name shit.
