Here's the thing: I don't bother citing statistics and facts and such when I encounter a BLM type. You can't reason someone out of an emotional position, so why bother? You can't "strip out" their emotions and replace them with facts. You can only replace their misplaced anger with well-placed shame. And here's the thing: this has only increased with time, not decreased. Information is more readily available, but I think you underestimate people's willingness to believe disinformation (also more readily available) simply because it makes them feel good.
Mockery is the only tool against them. This applies generally to SJWs, as SJWs always lie. They have no use for facts, only rhetoric. This, among other things, is a big reason why Trump took the country by storm last November. He fought rhetoric with rhetoric, while Republicans generally have tried to engage in good-faith debate. Republicans played a game that they couldn't win because leftists weren't even playing the same game. Trump played their game, and he played it better.
