I'll throw this in as a follow up to my previous post: The reason I think I felt it was unjust for a woman I liked to prefer another woman is that she was committing an offence against the principle of a woman giving a man not only the necessary help he needs, and being given back the help she needs in life, but also the gift of procreation, which she withheld from not just me but the whole of society.
What a ludicrous position! You are stating here that any woman who decides to abstain from heterosexual marriage and, indeed, any procreative sexual relations within such a marriage, is withholding this 'gift' of procreation' from 'the whole of society', In other words, by not so doing, she is committing an offence according to you. How sad then for those women who decide to remain celibate, as they are also condemned in your eyes.
I would assume that to be consistent this also should apply to men. At least that is where your argument leads. This could be a problem, you realise, if you accept the traditional view of Jesus, as not marrying and remaining celibate throughout his life.
Why not be honest and say that it is simply the idea of two people of the same sex having intimate sexual relations that you find offensive, rather than attempting to produce convoluted and ill thought out arguments to back up your prejudices?
