No, you're absolutely right. they have a right to be bad.

But they don't have a right to be objectively bad and simultaneously claim they are good and try to persuade people that lazy play is actually good play.

And I do have the right to kick them (I personally wouldn't unless they were prohibitively bad at healing to the point where we couldn't clear, but I do have a right to). And I respect other people's right to as well, and I'm not going to judge them or call them expletives for it either.
