So, if Harry Heilman had been kept out of the Hall of Fame instead of being voted in in 1952, because it had been found that he was a rabid communist I guess you would all have cheered, right? "Fuck you and your every other year batting titles you suckup to Stalin, you toady to tyrants!"
Because it's not just about being in the majority as you look around over your shoulder, right? It's about principle. And being a conscious advocate of an ideology that resulted in the murder of 100 million civilians in the 20th century, that would be pretty bad, right? Especially right when we were coming to understand the grotesque scope of the purges, murders and gulag archipelago. Even worse than once clicking "like" on the image of a t-shirt with an over the top sentiment.
When you decide that arguments with which you disagree should not be overcome but punished you step away from free society. When you delight in that punishment, and some folks here and elsewhere truly seem to do just that, you step further away.
