I doubt anyone is arguing that all those people who showed up were from Virginia. People from all over the states, especially the eastern half of the US, showed up for that rally. It's not like every person there was from Virginia. The Donald on Reddit had news about this coming event stickied for quite a while beforehand. And don't be confused, plenty of regular idiots who do support racism and can't see future false flags do show up to such events in significant numbers. There's plenty of regular Americans who support the idiocy that is racism.
