Closed to Christians./What Jesus said about homosexual "marriage."

It seems that the profession of counseling is now closed to Christians due to the glbt community's redefinition of marriage. Is this enough evidence to those who wrongly believe that homosexual "marriage" and religious freedom can coexist in America? They cannot. And since the United States of America was originally founded by those who wanted to worship God freely, the definition of marriage should NOT be changed since it would destroy that freedom.

The one-man-one-woman definition of marriage is from God, and is quoted by Jesus himself in the book of Matthew 19:4-6. (And interracial marriage is supported by the bible in Numbers 12:1-8) Doesn't America call itself, "One nation under God..."?
