So states can make laws to allow gay marriage but none to enforce federal immigration laws?

I don't get it. Dems have already made it illegal to treat illegals as illegals and now are forcing acceptance of homosexuality on the public when the gay community in America is what? Less than 5%? What's next Dems and gays changing all the text books in schools to add the human anus as the new sex organ? Or maybe force Sharia law on America cause God well I guess Allah forbid another minority group gets offended by the will of the majority here in America.
