Go about advocating genocide on the grounds that it'll stem global warming, save just one life, or benefit children, and see if people agree with you or if they react as though you're evil and insane.
Um, no. First, you need a great war. An all out war between the US and Canada is preferred. After the US is defeated, Canada can then impose strict and unfair sanctions against the US as a punishment. In turn, this will cause the American people to become desperate for a pay back.
Then, the Republican party would stand up and tell the American people that they are actually a superior race of people. The head of this political party will no doubt be another Bush. He'll blame the US's defeat in the great war on them gheys. After much debate as to whether ship all them gheys off to Hawaii or to take more drastic actions, a decision is reached to put them in ghettos and then ultimately concentration camps.

Occasionally, owing to the deficiency of the English language, I have used he/him/his meaning he or she/him or her/his or her in order to avoid awkwardness of style.
He, him, and his are not intended as exclusively masculine pronouns. They may refer to either sex or to both sexes!
