I remember the same concerns when Obama became the president of US. Lots of guys are saying that Obama will start WW3 but it didn't happen. Same thing on this one, him being a Muslim doesn't mean chaos. It will be an insult to the voters thinking of such.
I agree with you.
People are often to much emotional about some politics but they should be more concern about their own lives, not about things they can't change.
We live in democracy so accept it.
There are no first and second class citizens in democratic countries and everybody have the equal rights, to work, to serve country in the army, to be elected in some state office etc.
If anybody have problem with it, you should choose to live in some country without democracy, like North Korea, in order to see what happen if you don't give freedom to people.
There are good and bad white Christians and good and bad Muslims as well.
Please understand it.
