Also while /dup/ is filled with your classic insecure /pol/yps/, /tv/ is not.
You're not going to believe me but /tv/ really does have some entertainment industry insiders that frequent it. They regularly correctly predict Hollywood gossip before it happens. I don't think anyone on there is Spielberg-teir, but definitely some current and retired Hollywood middle management type writers, producers, and laborers. They mostly come across as veterans to me, since they can demonstrate some pretty impressive and deep knowledge of the entertainment industry.
Their racism and anti-communism is more of the blue blood variety where the inferiority of blacks, jews and socialism is just assumed. So they don't go on racists and anti-red screeds every 30 mins like a normal /pol/yp would. Things like the "le /pol/ face" meme aren't going to get to them and indeed I've seen them ignore such bait regularly, or even make genuinely funny self effacing jokes about it.
You're going to have to observe /tv/ for awhile if you want to successfully troll them.
