Gay marriage should be legalized In the United States

I know what the rules are, I was just stating the obvious. Contention 1: OverpopulationThe reason I brought up this argument is that many people that I have faced on this topic bring up gay marriage will slow the birth rate of an already overpopulated world. I had to go first in this debate and did not know what Pro was going to bring up so I made this argument so I'd be ready, but considering Pro did not wish to have a debate under this contention we'll just leave it behind. Contention 2: Homosexuals should not get married based on religious reasons. At first my opponent states that the Bible is against gay sex, but let's all be serious here. You get married and you have sex. Even YYW and Bsh1 are contiplating it. (. http://www.debate.org...) It's obvious that there is a link here. Marriage is in other religions as well. Such as Islam and Judaism. In Islam they also condemn homosexual marriage. (. http://www.billionbibles.org...) Many religious groups do not support Gay Marriage, but do support Civil Unions which I'll get into later. My opponent is incorrect on the 1st amendment as of a few days ago the Supreme Court Released it's Ruling on Religious institutions. The Hobby Lobby Case has implemented that companies have religious freedom and can't be enforced to cover contraceptives. (. http://www.tpnn.com...) You might be asking yourself now, what on Earth does this have to do with Gay Marriage. Well Ladies and gents it simple shows that the federal government cannot make people do things that can harm or interfere with their religion and that means Gay Marriage is now Unconstitutional. Since Marriage is actually an industry, because you can make a profit from it, that means gay marriage is illegal under the 1993 Religious Freedom Restoration Act. (. http://www.loc.gov...) Contention 3: Civil Unions My opponent brings up New Jersey, but he fails to bring to light how I proved last round that Civil Unions do work and Illinois is a huge example. He also drops how I stated that Civil Unions provided things that gay marriage doesn't in my last round. So I extend that across the board. He also drops the fact that many more people support Civil Unions compared to Gay Marriage. Heck, even more liberals support Civil Unions than Gay Marriage. Also, look to see how Collage grads support Civil Unions 21% more than Gay Marriage legalization. (charts above as source)Contention 4: Financial gain from Gay MarriageThis was my opponent's own contention that he brought up in his own case, but failed to bring it up last round. This is a dropped argument and you can obviously see that states make more gains from the legalization of Civil Unions then from the legalization of Gay Marriage that I have brought up in my last round. ConclusionIn conclusion, you can see that Civil Unions should be legalized over gay marriage for many reasons. Legalization of Civil Unions are better for the economy and more popular than gay marriage. The government cannot infringe on religions and doing so would in in violation of the first Amendment proved by the Supreme Court in the Recent Hobby Lobby case. Also Pro has Only brought up 2 contentions and has dropped his financial gains contention and by doing so has showed that Civil Unions are more economically friendly and beneficial than Gay Marriage. He has also dropped several arguments that I have made about Civil Unions being better than Gay Marriage.
