Yes. And I do. But you're missing my point here.
More often than not, such outrage is purely political exhibitionism for the express purpose of defending the Democrat party itself.
While you may very well be offended by it, the types who actually grandstand to express their outrage specifically in the form of claiming to be insulted by that particular language more often tend to do so specifically in defense of the Democrat party itself when the comparison is invoked. That blacks may be offended by it is just a bonus. But they're the ones openly making the assertion that they're insulted by the comparison and doing so as a matter of purely political activism. They don't care about you beyond your usefulness as a utility to that endeavor.
I understand that some blacks would naturally see them as some sort of ally, given the nature of the narrative that's attached to the endeavor.
But rest assured, they will throw you under the bus quicker than you can blink when the rubber hits the road and once they feel that your usefulness to their political endeavor has run its course.
