Sure but that's not the point. If someone gives good criticism, that criticism is good.

If you don't believe that, you're a tribalist.

The world gets better when everyone acknowledges and fixes their problems when they're pointed out. It doesn't matter at all whether it's a good person or a bad person that points them out, what a gift it is for someone to show you your flaws.

The issue is the amount of bad faith critique levelled by people on the right. Supporting one of their valid criticisms without mentioning that they are normally full of shit appears like a blanket endorsement even though they may bring up only a single good point it’ll be seen as complete support.

Ya sure but that isn't really what your comment was saying which was more along the lines of "ignore all criticism until you know where it came from".

Anyways, if the criticism is valid, you are just plugging your ears at that point.
