Second, oppression is not an absolute, it is a spectrum. Are gays in America as oppressed as the Jews were in Nazi Germany? No. But that doesn't mean they don't face some degree of oppression, particularly if they are also a minority or impoverished. This game you are playing of arguing that gays equate themselves to slaves and Holocaust Jews is equally insulting and intellectually dishonest.
Third, oppression exists for gays in many ways. I've experienced housing and employment discrimination on the basis of my orientation. So no, it is not just a marriage issue in this country.
Fourth, I find it absolutely hilarious given the persecution complex that you and many Christians in America have displayed to take such a disrespectful and dishonest approach towards this discussion with the gay community. Apparently you face terrible oppression as a Christian in a nation that is over 70% Christian but you can't imagine how a sexual minority that equates to 8% of the country could face any degree of oppression. That is laughable.
