This is the problem I see and likely the problem the author sees even if he's veiling it. The left wing specifically keeps disregarding other peoples views wholesale on a reputational basis. When I make posts online left-wingers regularly dig into my post history to find a reason to discredit me while right wingers don't even bother looking. If I'm making a right-wing point just like the author I go to pains to obscufate the fact I'm making a conservative argument. Otherwise making the argument is pointless because your intended audience, those with left wing views, won't read it.
I don't mean to make a completely partisan shitting on the left post. I have voted left wing in every election I've been a part of. I blame the uptick in politically motivated violence on the right. I believe "scientific racism" is increasingly becoming mainstreamed on the right through "red pills" as an explanation for say why inequity in employment/crime stats exists and is fair.
However holy shit merely talking to the right these days can cause a whole bunch of people to hold you in contempt. It ultimately will and has backfired because it's entrenching intellectual blindness which is bad for the left and bad for society.
