"Truth and facts are not hate speech."

Yet as you pointed out, the truth doesn't belong to you. So what is it, exactly, that you're offering?

It's trivially correct that truth and facts alone can't be hate speech. It's also true that the best propaganda always contains facts. What propaganda doesn't do is give ALL the facts, presented in a balanced way. Hate speech does the same thing. It hammers on the faults of a group- which are typically the same ones you can say of any group- over and over. After a relentless barrage of selectively chosen negatives comes the kicker: "We have to push back. If we don't, we're done for."

I could write you a litany of facts about Western Christians that would whiten your hair. And if that's all you ever heard, you would come to fear Western Christians. From that point, encouraging you to act against them would be easy.
