You must be joking, right? America is not tolerant. Look how many posts in this forum alone decry Antifa. Or look at how many people get up in arms about having a black history month, or an Islamic worship center popping up in an area, or a bakery baking a cake for a gay wedding. Yes we are less violent than some less tolerable places but that doesn't mean we are a tolerant country.
We have all heard the age old argument, mainly about healthcare and gun laws, that if you want to be like (insert country here) then why don't you move there. To which the rebuttal is always because this is my country. So America is my country. I'll worry about what WE do.
