"I'm not a democrat though" Someone explain to me what is wrong with identifying as a Democrat

I see many YouTubers and podcasters as well as everyday people refusing to identify as a Democrat. Yet, when you listen to them talk and they share who they vote for, it is almost all democrat policies and politicians. It reminds me of when people were ashamed to identify as a feminist. People would say "I'm no feminist, but I believe [insert rights you believe women should have]." Why is their such disdain for identifying as a democrat? You will never hear people on the right saying they are not republican or conservatives.

If you primarily vote for democrat policies and politicians, then identify as a democrat and stand on it! That is part of the resistance too.
