Tolerance, diversity .... CAN be a good thing if it's handled / applied correctly. When coming to the USA people should be able to maintain their beliefs, customs etc... BUT they MUST become and assimilate as an AMERICAN FIRST, and they don't seem to want to give this courtesy to others on the same level they want it applied to them.
Diversity can be good, but it's a slippery slope that can can get way out of control when you throw in a 1st and 14th amendment and combine that with other laws/ provisions taken out of context by liberal - socialist- communist leaning judges.
But we Americans have allowed it to be done to us, ultimately we are to blame.
