By "they" I believe you are referring to the Democrat Party (and many in the Republican Party). And Islam is not a religion. It is a conquest ideology.
I'm talking about Radical Jihadist, Marxist, and those that have sold the Country out and are too stupid to understand you can't control the two ideologies once they start spreading like wild fire.
This is all a Color Revolution and I recommend people to stop fighting over stupid **** and look at the bigger picture before they end up living under Sharia Law or Communism.
