Another verse taken out of context.
Jesus was talking about divorce there, not monogamy.
I have yet to see another religion that is so opposed to marriage as Catholicism.
Monogamy is relevant here, since no-divorce marriage is the same as monogamous marriage.
You can see how shocked the Apostles were by this teaching. Especially since He said this was the unchangeable nature of marriage, because --- nevermind Moses --- it is GOD who joined the man and the woman together. GOD is the basis of this unbreakable bond.
This is what Christ said, which is reflected in the teachings of the Church.
If you find this "anti-marriage," you'll have to take it up with the Author of Marriage.
"Another verse taken out of context..." Jesus was talking about divorce there, not homosexuality."
Again, I reply that He was not talking ONLY about one disputed question or another. He was making a fundamental, all-encompassing point about the nature of marriage itself. He does this by citing how it was "in the beginning": Man, woman, exclusive, faithful, lifelong.
