Confessing to fucking goats isn't quite the power move you make it out to be, but if you want to take one for the team, and claim that what you're doing is merely performance art intended to troll, while "things aren't as bad as they're being made out to be" and "concerns about replacement" are actually well founded, then be my guest. The fact that a racist doesn't mind being called a racist doesn't make them not a racist.
I don't think you're reading me in the way that I intended, and I think you're being very uncharitable.
I did not claim that their concerns about replacement were well-founded, merely that they were understandable. Again, go back and read what I actually wrote: we cannot both acknowledge that there is a decline in the proportion of whites in America, that there are policies being pursued that help with this (again, no moral judgement, simply a statement of fact), and also that the people who are scared about losing majority status are completely without basis in their concerns.
If you cannot understand the tiny pier of truth that these people use as a foundation for the massive pile of other nonsense they've stacked (or had stacked) upon it, you will never be able to get them to change.
I'm not asking you to agree with them. I'm not asking you to say that the whole of their beliefs makes any sense at all.
I'm asking you to understand that they aren't pulling this completely out of thin air, and that if you want to have more success than you've had it may be worth it to acknowledge their concerns and try to show how your preferred policies would serve them better and how their current preferred bozos are manipulating them.
You and people like you might assert that they're idiots, misinformed, evil, or whatever else--but their vote counts as much as yours, sometimes moreso, and so you ignore or misunderstand them at your peril.
