Keep in mind re: Stephen Miller hand thing that the pictures in the tweet are showing two different prison gang signs.

1 - A prison gang sign made with one hand only, specifically with the thumb pointing out

2, “The Peckerwood” made with both hands but the fingers crossed on one hand.

It’s possible he’s trying to be slick by using some combination of both but how recognizable would that be? I doubt Richard Spencer knows much about WP prison gangs, for example. So I’m still skeptical of this being like the “ISIS finger point.” I guess I would expect to see more comments about this from actual racists that are supposedly watching these press conferences who are meant to pick up on it.
