there's nothing wrong with not constantly exposing your friends when they fuck up from time to time. we all do. HOWEVER, if one of your friends is actually doing something illegal and you keep supporting them, you're no longer not involved. you're part of the problem
and even if it's not illegal, if it's something completely unethical or that you CLEARLY should not be supporting and you decide to not only keep doing content w them and be friends w them but stay silent on the matter, you're part of the issue at hand
