I don't think the internet works that way. It's all or nothing for everyone at every time.
I mean, look at it this way: If you were a part of a group he said some bad shit about, you'd be pretty pissed, right? Or, if you were a friend of someone who was, you'd probably still be pissed because you love and support your friend. Now, in life we are all going to end up supporting things that are shady or promote bad things, you might use a Nestle product or shop at Walmart, this stuff is inevitable in most cases. In this instance, it's a product that nobody is really forced to take part in, it offers little tangible benefit beyond entertainment, so in a case like this it's much easier to take a stand to not support it because it isn't a necessity.
I don't think everyone who watches it is a bad person or anything, but once you've learned about things the guy said and still actively seek out to defend it, then I would start to side-eye because it's basically saying "I don't care about those issues or people, I value my own entertainment more".
