When you take a moral stance, on some level you're accusing others of taking an immoral stance. When you fight for justice, it must mean some people are unjust. There's not really a way around that unless you draw really vague boundaries.

I grew up hating the use of pathos in argument. I always thought that we should accept an argument on its merits, not because we liked it, certainly not because we liked the speaker.
