I am aware that conservative posters often trot out the “you’re just criticizing me because I don’t agree with the liberal orthodoxy” line. I am also aware that this is often used to divert any accountability for one’s actions. Indeed, it appears to be surprisingly useful to be able to say anything one likes, no matter how objectionable, and then claim any negative reactions are purely partisan.
In Bricker’s case, while he was sometimes Pitted for partisan reasons he was also often Pitted for more specific behaviors.
As already noted above, the words “a different perspective” may have to do a lot of heavy lifting depending on context. “Biden is a bad president” is a different perspective, but so is “Transgendered people are mentally ill deviants” or “The Holocaust was a hoax”. Not all “different perspectives” are created equal.
