The national kind, yeah. Common knowledge. See above statement about how awful he was.
I am aware you’re specifically referring to rush’s specifically anti-socialist dint. But by suggesting he was a fan of socialism, you’re committing to the same fallacy as he tended to, where he would equate socialists (from USSR so obviously they are mega socialist, and fans of the purges, read authortarians) with actual socialist ideology.
The grand irony of rush is that his solution to authoritarianism was authoritarianism.
Entirely reasonable, and likely successful. There are however a bunch of weirdos here, and a bunch of people that won’t understand the reference cause they do t remember the guy. No seriously, we grew up with him, but that was ages ago for the young’uns these days.
