I don't disagree with what you're saying regarding cross purposes, however there's a viewpoint missing: that of the person who doesn't believe black lives matter, either on purpose or on accident.

Liberals eating eachother alive and liberal movements being terribly disorganized is certainly an issue, but what I'm arguing against on here is people denying that BLM has ground to stand on. blacklivesmatter.com not having been updated in like, 3 years, is separate from that issue.
