I dunno, why do people typically try to "both sides" the endemic problem of white supremacy in the US? Couldn't possibly have something to do with the same people's automatic instinct to just happen to take the side against people who are demonstrating for social reform? Or maybe the compulsion to come into a thread about systemic racism and, as Themius said, make it a pity party for white people facing "racism" despite there being no system of oppression or erasure set up against them.
Honestly, I blame South Park. An entire generation of young men have had their minds poisoned to hold all strong political beliefs as equally worthless, and have developed a gut reaction to assume that anyone advocating too enthusiastically for a given cause must be irrational or unreasonable because caring about things is a sign of being a bluepill or whatever chuds term it now that the Wachowskis have reclaimed the term redpill.
