Rhetoric only works when it plays on people's emotional insecurities. For instance, a griefer in the Periscope said "Stop acting like you've read more than ten books". The author of that rhetoric was assuming this would play on either Vox's insecurities (about his intelligence) or his audience's (about their own intelligence, or their confidence in Vox's intelligence).It was rather amusing. Read 10 books? I once read 70 in a month for the MS Readathon. Anyone can see right on my blog that I read more than 50 every year, as well as precisely which books. My literary consumption is not exactly a point of insecurity for me.
The rule "SJWs always project" comes from two attributes of SJWs: 1) they are solipsistic and thus believe other people have exactly the same insecurities as they do, and 2) they want to trigger other people's insecurities with rhetoric. This leads to them attacking others in the ways that would be most effective for others to attack them.
The reason "You have to go home" and "You have to go back" work so well as rhetoric against civic parasites is that they play on a parasite's most fundamental fear: being removed from the host. Parasites without hosts have no future.
