The Catholic sexual morals are about required behaviour and condemned behaviour, not a description of behaviour (or "fact-claim").

I am not sure that the official Catholic sexual moral requires systematic lying about fact-claims to support. It is a condemnation of many forms of human sexual behaviour. That is not so much a fact claim as setting the rule that the behaviour is undesirable. I am very much in favour of involving the Catholic church in debate about it, from the outside and from the inside, because we agree that in reality the undesirable behaviour is that of the church issuing these ratings and rules. I criticise parents who tell their children to behave according to this dogma, but I don't think their behaviour is necessarily abusive. I wouldn't remove the children or so. Their behaviour falls neither in the category of what I approve of nor in the category of what I want banned. There are several loathsome doctrines around which do not have any place in civilized society as I want it, but one must tolerate that people adhere to them.
