That's like saying pedophiles/homosexuals in the catholic church are that way because of celibacy. What this law has done is simply legalize 'sexual activity' between two persons of the same sex .....has nothing to do with divorce rates, contraceptives etc. It has to do with men who have turned their back on God and become sexual addicts as well as exhibitionists.
They have sex for mutual satisfaction on many levels, but not for the procreative purpose which is, by God's design, its structural, psychological and spiritual core.
They can't explain why sex should just be between a man and a woman, because if fertility isn't a factor, the different anatomies have no significance. "Gender" (as they call it) has no significance.
People who have deliberately ditched this level of significance (contraceptors and sodomists) will eventually be having sex with warm, responsive, rechargeable Japanese androids, and "person" will have no significance.
and you said...
"That's like saying pedophiles/homosexuals in the catholic church are that way because of celibacy."
No, that's not like saying that at all. Not even by analogy. Not even close.
That sentence is not an argument, it is a fact.
