I admit to not having a clue how other people think unless they tell me. The gal behind this campaign tells me exactly how she thinks in her rants on the fundraising page. For that matter, so did that the guy behind the flag protest, if I am to believe the media reports.
I don't hate people because of their tan lines. That'd be like hating someone because of their hair color. Why? What's the point? There are plenty of reasons to dislike someone, reasons that have everything to do with how that person acts, thinks and talks.
That kind of stuff can be controlled. You can control what you say. You can control what you think. You can control what you do.

You absolutely cannot control who your ancestors from 100 years ago happen to be.
Control what you can. Let the rest slide.
When it comes to the stuff you CAN control, yeah.
