I live in the United States of America. I believe that our Constitution protects equal rights for EVERYONE in our country. That means that if a gay person cannot marry the person they love, but a straight person can, they are not equals. Therefore it is in direct violation of the constitution not to allow gays to marry.
Personally, I believe that each person should choose their path and that others do not have the right to decide what is right for anyone but themselves.
Although I agree with the sentiment behind this post, I disagree with saying that this is a violation of the constitution since technically it is treating homosexuals the same under the law
as the law is written. If a homosexual male tried to get a marriage license with a female and was turned down because he was gay, then that would be a case of unequal protection under the law.
The issue is that you're talking about equality under the law (which is true), but then you term "marriage" as being between people
in love instead of using its term under a more strict, legal definition. Under a more legal term, marriage is just a contract set up under the government for purposes of further clarifying other laws that use the term "marriage" in the legal sense. As such, the government can define what constitutes a legal marriage... And because this is just a legal definition, people don't have it as a "right"; rights are allowances that people innately have even without the constructs of a government. So you have a right to travel wherever you want on the public roads, but you do not have a right to a driver's license as the driver's license is just a government construct. Similarly, you have a right to the pursuit of happiness including the right to associate with whomever you want; however you do not have a right to a marriage license.
To put this in a different way, if the question was whether homosexuals should be allowed to date, be in love with each other, make love, co-habitate, etc. then this would definitely be an issue of equal protection under the law. This is why the Supreme Court struck down sodomy laws as they felt that how people chose to engage in sex (esp. in a private setting) is outside the purview of the government.
Now because most people use your definition of marriage as being some special union between people in love, it is very easy to see why so many people are talking about their right to marriage.... What they (and I suspect you) are actually saying is that they feel that homosexuals have a right to love whomever they want. And in this respect, that is true. That is why I feel that some of the marriage laws should be broadened to define marriage more along the lines of who a person wishes to live with regardless of sexual orientation.
