Why can't we all just be nice?

So, we have group X. They have a cause (sexism, racism, the environment etc). You support this cause in principle, but don't like the way they pursue it. That's fine, but there are certain arguments which result from this situation which come up again and again and I thought I'd address them here. I've been pondering it for a while but this was a big "inspiration" :/

Note that if you do have a problem with that cause then that's a different thing, though then you still have to be careful not to conflate the medium with the message so the arguments below are still problematic. In fact a lot of the time I think people use these arguments (especially the last) to mask the fact that they don't want to support group X, but aren't willing to say that due to peer pressure or not having any rational argument beyond "It's hard" or "it makes me uncomfortable".

( They're just not nice )

( It's in their own best interests to be nice )

( They have a moral obligation to be nice )

( If they're not nice I'm justified in ignoring their cause, maybe even actively opposing it )
