The people he's talking about are beyond the pale. He's fine disagreeing with people, he even likes to have his point of view challenged- it's just that these people are a step too far; they're not just wrong- they're evil.
An answer is: I've found the people you ACTUALLY disagree with. Insofar as you can be said to hate anyone, it's the people you would gladly exterminate- and feel good doing so.
Disagreement with someone on a matter of import automatically causes some small amount of dislike for them. You can still like someone overall! But if they're a great person, except e.g. they think abortion should be illegal, you'll still think less of them than you would have otherwise.
My argument is that this dislike scales with how much you disagree with someone; and so, all else being equal, the people you hate most are the ones you disagree with the most strongly- to the point that a will awakes in you to engage against them in righteous wrath.
You see it in the twitter mobs and the witch hunts of old: If people decided to crucify someone, say by going after their livelihood- if, somehow, they thought that was the best way to improve the world- they should do it with their eyes down, shaking their heads, crying "If only it didn't have to come to this- but if we didn't do this, you would have caused even more pain than we. This course of action is a tragedy; but any other would have been worse. Forgive us, but for the good of the nation, you have to die."
They don't- they go after people with glee. It's fun, it's exhilarating; it's a fox-hunt. You can read it in people's testimonials about being part of a twitter job-lynchmob: Everyone enjoys it till they're the one on the chopping block!
Real Disagreement, as I would call it, is that kind that honestly provokes the aforementioned emotion: the desire to see someone destitute and homeless, if not dead, and the frame of mind where you could look at the result with pride. I'd call that hate.
(You can hate people for other reasons, of course.)
