Why so much hate for Carmela??

Whenever I have a question about some interaction or some moment in the show I would search for awnsers online and would be brought over to this subreddit. Whatever question it was, there was always some serious hatred for Carmela. I get she has her issues, like all the characters, they are all very complex and well written, but Carmelas flaws are alot more grounded, like, she's a bit vain, or she made a mistake when she was a teenager by being with Tony. I mean, I see as much hatred for the woman as I see for Tony or the other guys who do some fucked up shit during the whole show. Christopher is literally a woman beater and a killer! Sometimes people just hate on her because she's a stay at home mom, like wtf? My mom was a stay at home mom and she's wonderfull. She's not "lazy" like I've alot of people say, she raised those kids and food was always on the table, she was doing good. Idk, the hatred for her seems so blown out of proportion! I just don't see the evil everyone else seems to see in her.

Sorry if this is a tired topic, I just got into the show last month.
