I mean, in the early days of TV sure, I know people in the 50s used to send blankets to an actress because she played a character that was poor and they would throw mud at the actor who played her husband because he was an asshole... But these days? Dang, get over it, they're just doing their job!
I guess, it is kinda a human trait to (mis)associate the character with the person behind it. I get what you're saying, though. But maybe it's also a compliment towards the actors
