The answer should be the same as mine which is that you aren't to discriminate against them. If they don't give the answer of "equality under the law" then they need to go back to re-read their Catechism once again.
Herein is the problem and it is multifaceted.
First off, as human beings, even homosexuals have rights and the right to be treated equally under the law.
Secondly, if they are to be treated equally under the law, that means you don't get to treat them as second-class citizens.
That doesn't mean, however, you get to legitimize the homosexual act. That is precisely why I have asked you before, "What does sexuality have to do with the Military? It is not a social club."
Think of it as an expression of the Golden Rule. If you want to be treated as an "equal under the law" then you have to treat others the same way.
You do not have to legitimize their sin. You do not have to acknowledge their sin as being proper. You do not have to accord them any sort of special status. But you do have to treat them as human beings.
Otherwise, you run into the problem where the Golden Rule works in reverse. "As you do unto others, so shall they do unto you."
That sort of society where people are constantly at each others' throats and designating each other as second-class citizens depending on who is in charge at the time is not one that I would want to live in nor is it one that I want anyone else to have to live in.
The problem with your argument is that you are arguing that marriage is a constitutional right. It is not.
Depriving someone of marriage, is not the same as treating them as less of a person. No one has the right to get married to whomever they want. Not you. Not me. Nobody.
Positive discrimination is permitted. That the state regulates marriage as one man and one woman isn’t discrimination against those who do not get married. It IS recognition of their bond and provides legal protections encouraging the formation of families and children.
That’s really the core of the argument here. The state has an interest in healthy families, and the best way to get there is through marriage.
Finally, a straight answer, you are wrong about a (good) Catholic supporting homosexuals in the military and gay marriage in the military, but it is refreshing to see you admit to it.
It was only 1994 when Clinton made it legal for a homosexual to try to pass in the military for as long as he could until caught, it was only this year that Obama made it legal for them to serve, and then fully equal with “marriage”.
So you are a part of this new world for the American military, you reject all that was before in regard to homosexuals in the military.
