Gay pair to adopt children of unfit Catholic parents

[kılıç_mehmet]

Mehmet: first define 'normal'.

The normal way of things that were done until today. The concept of family.
Since children can only be produced via coitus of a man and a woman, it has been assumed the norm that the people who made them should be the ones to raise them.
And in the case of adoptions, the same norm of a father and a mother has been applied because its the normal way to do things.
Why is it so hard to comprehend, or rather, to accept?
