The problem is what you're linking is something you personally disagree with, but that doesn't mean it's "bait" in the first place. (I probably should've avoided a political example as I think some are getting carried away with that, but it could be anything.)
Different example: I could link something about peanut butter though I hate peanut butter with all my heart and hope it ceases to exist. Yet you'd never call "peanut butter cookies recipe" engagement bait. (Well, probably never...)
The term or phrase has to encompass more than just political sides or something like it. It's the act of spreading something you personally don't want to spread. But what you're helping spread could be benign from most people's perspectives.

It also helps move your page to the top of searches. AKA, SEO or "Search Engine Optimization". Now, why it does that I have no clue, but Google algorithms decided it was important for insert reason... ???
