Has Lil' Ben actually ever made any coherent arguments for whatever passes for "conservative values" or rebuttals of anything to the left of him?

Depends on your definition of "coherent". He has to leave stuff out, misrepresent and straight up lie because he's arguing for things that are morally, factually and philosophically wrong, but he's good at being a debate bro and he's capable of logical thought more so than morons like Tim Pool, Steven Crowder or Matt Walsh. Especially if you compare him to Michael Knowles, one of the other Daily Wire bozos, Shapiro comes off as way more intelligent.
