A: Racism sucks!
B: Yes, but being falsely accused of racism sucks, too!
Insert "sexism" or "rape" or whatever noun fits the particular situation; it's a one-size-fits-all comeback.
That response is true in the sense that it's not completely wrong, but the problems are so radically different in scale and scope that the effect is to lie.
Here's what these people are effectively saying:
A: It sucks to starve to death.The fact that two things are both not-good does not mean that they are the same, or that they cancel each other out, or that they are even comparable. If being "falsely accused" of something doesn't involve actual law enforcement and at least potential jail time, it doesn't count.
B: Yes, but it also sucks to lose my morning break and have to go hungry until lunch!
Look, white guys, here's a good test: if you're about to deploy an argument, ask yourself if John Wayne would say that. (Anybody who would use this line of reasoning, I'm pretty sure, is entirely cool with the Duke.) Would he whine about being falsely accused of something? No, he would not. Follow that lead.
