Why the denny hate?

So I was a huge Nascar fan from 1998-2020. When I stopped watching, denny had some haters but not a ton...Kyle Busch was probably the most hated driver at that time.

I just picked Nascar back up this year and I'm baffled as to why so many people hate him now.

Did something happen in the last 4 years? Or is it a generation thing? Like they view denny as a "get off my lawn" old timer lol. The only 2 things I can personally remember was chase Elliott at Martinsville and he had a fued with Ross for a bit, but that's it.

Denny and Joey are both neutral for me but I understand why Joey rubs people the wrong way. I don't understand the denny hate. Especially at the magnitude that it is lol
