I laugh in the face of White Supremacist groups

[Askthepizzaguy]

I'm just saying if they really believe black men are out to get the nice little whites

Then they are correct. Some of them are. And there are a lot more whites out to get them, according to the sheer amounts of white-on-white crime. It's ignorant to fear only one group.

then that's not really any more different from how you would hate Stalin for mass-murdering everyone he didn't like

Yes it is. Opposing a mass murderer is different from hating an entire racial group. There is zero comparison to be made between them.

Presuming you do disapprove of the likes of Stalin

Yes.

would you hate him with the same hatred Hitler had for the Jews? Or would it not be more of a strong moral disapproval?

It's a meaningless hypothetical. Stalin is dead, and a mass murderer who is guilty of crimes against humanity is, and always was, different from a "race" of people. I strongly and morally disapprove of what he did. And I wouldn't even characterize my dislike of racists as hatred; only disappointment and a wish that they would relent and become less ignorant.

If I hated them, as they hate minorities, I'd be calling for much worse than speaking out against them. There is no comparison between what I feel towards racists and what racists feel and do towards those they oppose. I'm dismayed by what you're saying, and wonder what drives you to defend supremacist groups from legitimate concerns that rational people have against their divisive and hateful behavior.

I don't think you're putting forth a reasoned argument, and I don't believe there is a moral reason to defend racists at all from being correctly labeled as hateful.
