He probably does want Republicans to go extinct.
If there's one thing extremists, left and right, have always managed to do, it's invent enemies. Jacobins had the Vendee and the calendar, Nazis had the Jews, Soviets had the generals, doctors, Ukranian land-owners. Khmer Rouge had the teachers. Interahamwe had the Tutsis.
Once the DSA bans the Republican Party as a hate group, they'll go after the bankers, rural America, "toxic" men, and anyone they label racist. They will always have an opposition to invent.
My deal is that, in all seriousness, you have already shown yourself to be a dim-witted person, and I see no reason to do anything other than insult you.
Nobody asked you, Don Quixote.
