In the face of the caravan of immigrants heading toward the United States. Yes, it's hateful rhetoric. When you define an opposing view as hatred, then unless you can prove it's because they truly hate, you are the one being hateful.
The word 'hate' has become a smack down. It's the post-modern equivalent of Archie Bunker's 'stifle yourself!' It's meant to end debate and hand the trophy to the winner. In this case, those who are advocating open borders and post-national globalization. If you aren't with them, you're a liar, a hater, a bigot, a racist, a Nazi.
And that, children, is hate. Not opposing such positions as globalization or open borders (or, for that matter, supporting them). But framing salvation and righteousness as only capable if one supports your own opinions. If it isn't hate, it's the next best thing.
