The terminology “intrinsically disordered” (objectively is not normally used) signifies that (a) it is inherent in the condition and (b) it is inconsistent with God’s plan, in this case man and woman and procreation.

It is not a moral judgment nor is it hateful. It is a sterile assessment of a particular orientation which makes it clear that acting on it is inconsistent with the moral law. It is also a direct translation from the Latin.

The Church has repeatedly stated that the orientation itself is not immoral and that those who persecute or deny rights to others based on orientation alone are themselves committing a serious sin.

If you can come up with a better phrase, please share it.

One of the reasons it is stated so starkly is to dispel any notion that the Church will change its teaching on LGBT sexual relations, which as you can read any day on this very blog is still hoped for by some few.
