Honestly what is there to do? They're chasing the Jackson/Holder/Obama/Sharpton boogeyman. Sharpton isn't even scheduled to show up. They're literally protesting something that isn't gonna happen but they'll claim some kind of moral victory because a rumor got started on a conservative blog.
This happened two weeks ago in front of a mosque in Phoenix. a$$hole gets on YouTube popping all kinds of shyt, shows up with a bunch of open carrying flag waving "Patriots", and then starts a GoFundMe to "protect his family" and continue his crusade of bigotry.
These people don't change their minds. They aren't swayed by evidence or counter protests or reason. They're the intellectual and philosophical children of those crowds in lynching postcards. Confronting them is little better than yelling at a wall. Like with the protest at the mosque, they will be a lot of heavily armed, pumped-up-on-patriotism, angry, racist but not racist, take back my country, Texas pricks of the highest order in attendance and they will all be looking for trouble. Recipe for disaster.
Long story short this is a temper tantrum and a fundraiser for a bunch of conservatives who can't wait to shoot someone. Nothing to be gained, lots to lose.
