I think there seems to be extensive confusion between the terms “illegal” and “socially unacceptable”. There are tons of objectively and widely agreed-upon reprehensible actions that are perfectly legal. The argument “but the law is clear on this matter”, is largely irrelevant in the context of the conversation we are having here.
