Homoaffectionate couples (at least if they are what I think you mean) are not allowed. Good and firm friendships between individuals of the same sex no matter their inclination are naturally permitted, but when that takes on an erotic dimension then that relationship is beginning to walk a very fine line. I would not think a relationship of the sort I think you mean would be looked on with favour even if it does not outright fall into the sin of homosexual acts.
Furthermore just to mention it, gay "marriage" and any sort of attempt make such a union equivakent to a married couple is reprehensible and condemned.
As to your actual question though, the answer is: NO
A child deserves the privelege of having a father and a mother. This is also vitally necessary as a child requires models of both femininity and masculinity in order to learn develop properly their own masculinity/feminity and to learn the proper manner of inter-relationships of those of the opposite sex. Without this, the child is ultimately deprived and one would be actually harming the child by raising it within a relationship structure that is incorrect.
Indeed I personally think that a great deal of the problems in contemprary society is the result of the failure of a previous generation to recognise that male and female are distinct and separate and that they work in complimentarity. They are equal yes, but that equality consists in differentiations of function and being that together form the sum whole of the human experience. One can simply equate male and female as being the equivalent to each other to the point that the duality of male in female is redefined merely to a question of "gender".
Just for the sake of argument, what if the choice is between being adopted by such a couple (Or even a real gay couple) or being left on the street?
I fully understand and agree that a kid would be best with a father and a mother, but it obviously isn't reality that every kid get that, otherwise they wouldn't be orphans.
So, barring that, I'm seeing a few different choices for a kid that won't be getting a home (Listed in random order to be sorted out later, and these options include options that are clearly sinful. This is only a list to sort of sort out the different options for a kid who won't be getting a father AND a mother.)
They could be raised by a gay couple (Sexual or non.)
They could be raised by a single parent.
They could be in and out of foster homes.
They could be left in an orphanage.
They could be raised by parents who are neglecting their kids (Which goes to show that a father and mother don't inherently make a family "Ideal" in any sense.)
Or even (Heaven forbid) they could be aborted and never get to be born at all.
While I'm no friend to the "Gay agenda" if a gay adoption needs to happen to stop a baby in the womb from being murdered, I'm all for it.
Even leaving the kid in an orphanage or in and out of foster homes doesn't seem as ideal to me.
While a gay couple isn't really a real couple (In my opinion, and I'm guessing the Vatican agrees with me) if the absolute worst thing you can say about a situation is they are being raised by two males or two females, that seems a better fate than most of the fates above (The single parent may or may not be better.)
Therefore, I do think that the post I quoted above is being very "Idealist." There are a LOT of problems in homes, and speaking for the child's growth alone, I'd consdier gay parents to be a somewhat minor issue, at least in comparison to being neglected, not having a consistent home at all (Foster homes) or (Heaven forbid) being murdered before ever seeing the world at all.
I do await a response to this, as I do think its a subject worth defining.
PS How do you feel about me being homosexual?
It doesn't change my opinion of you at all really. Homosexual incliations are a temptation, not necessarily a sin in themselves. And I don't necessarily see anything wrong or "Contradictory" about saying that homosexual acts are immoral, but you still struggle with the temptation. That's reality. We all have temptations, and most of us fall into them very regularly.
That said, I do question why you would want to "Identify" as gay. While there are a lot of people who struggle with homosexual attractions, most people who "Come-out" as gay are usually OK with the fact. You yourself do seem to be a bit confused about how to handle it.
I don't know what the Catholic side of Christianity has to say about it, but I do think that identifying as gay is the incorrect response, even if you intend to stay celibate. I don't think homosexual attractions are sinful, but its not something to embrace either. Its a temptation, every man has been tempted, even Christ himself. And if one should fall, that person should repent, and God is faithful to forgive.
And on that note, to add an actual question, rather than a comment, are a large portion of Catholic priests gay? I ask because priests have to be celibate, so since gay Catholics are expected to be celibate as well, celibacy wouldn't be an additional sacrifice for them, since they have to do it anyway.
