Yes, homosexuals are not equal to heterosexuals as far as qualifications for marriage goes. Neither are children equal to adults, or qualified for marriage. Neither are close relatives qualified for marriage.
What makes you think heterosexuals are qualified for marriage by default given the number of heterosexual couples that end up divorced.
Marriage does not depend upon the sexual orientation of a person but on their ability to compromise and work together with their partner to
deal with the lifelong changes and challenges that are not apparent to the single person.You can dearly love a person with all your heart ,be commited and caring and able to grow with them and still not have a succesful relationship because it requires the participation of two.
Sexual orientation is a vanishingly small part of what is necessary to a good marriage over the entire course of couples lives.Furthemore, the guaranteeing of gays rights to marriage under the law cannot be of any consequence to heterosexual couples since it has no impact whatsoever upon the success or failure of their own marriage.
That said the rights of gays to be free from distrust and persecution is something that must be accomplished in order for humanity to ever have any even meagre claim to civilization. You do not like gays ,fine,I do not like incoherent bigots but they have must have the same rights under the law as I do regardless. { a note here I am NOT equating you to the incoherent bigot}
If I am appaled at something that is MY problem and my emotional response is under my control and not dependant upon the actions of others. We quite often forget about this shoertcoming of ours in our relationships but this is what the point of law is basically, to protect othesr and ourselves from ourselves.
