The committee seem to think of morality as leading to repugnancy. This is clearly the committee's biassed perspective. The basis of religious morality is not repugnance, it is right and justice. The committee is living in cuckoo land if it believes that there can be law without morality. The committee sets up its own morality in the report.
Morality is about what is right and wrong.
The members of the committee are rejecting religious morality. They are putting up their own version of morality. They do this in a devious way, without recognising that they are replacing one set of morality with another. A pervading influence in the Committee's work is the repugnance which is felt towards religious morality. This makes the work of the Committee repugnant to common sense, wisdom and human progress.
