People who come to the US almost universally accept American values after a generation. And considering large proportions of the US believe LGBT people don't deserve to get married or adopt children, and several trans women were savagely beaten last month in my city by some white-bread born in america nazis, that many people born in this country think doctors should be able to deny care to LGBT people based on their religious beliefs -- meanwhile everyone I know who's immigrated from a different country has been nothing but wonderful to me -- I would argue that believing immigrants will somehow reverse progress on civil rights is ridiculous and not justified by the facts.
