While this is true, there are also plenty of progressives, both on this board and off it, who will be sure to tell everyone how horrible and unacceptable racists are, and that it would be better to suffer 1,000 more years of Trump than make any kind of concession towards them (okay, that’s an exaggeration - but I’m sure you know what I’m talking about). There appears to be a certain amount of equivocation going on here, where racism is both universal and unavoidable - something you shouldn’t be upset about being accused of - and also the worst thing in the world, with racists deserving of public shunning and being left to starve in the streets.
There’s also the issue that common conservative views around personal responsibility, the limitations of government etc, are fairly frequently seen as racist in themselves by progressives. It should be obvious that conservatives (or any other group, really) are not going to instantly change their minds and apologise just because someone on a message board disagrees with them ideologically.
