Yes, you have. You use the word 'valid' repeatedly. What could that word mean in this context apart from 'acceptable' or 'good'.

I reference Catholic moral theology because it is a longstanding moral tradition in our culture which clearly draws a line between judging whether something is genetic or 'natural' is different than judging whether it is good or bad. Catholic moral theologians think that it is a least possible, if not likely that homosexuality is not a choice, but this does not cause them any problems in judging that it is not good.

Not sure exactly what you mean by that, but I've come to appreciate the sublime satisfaction that is achieved from hitting the mark!

How about we rely upon the common convention known as the dicionary, you know that researched, validated and published volume of work that purportedly evidences a broad agreement as the the possible meanings of particular words as understood and accepted by a plurality of any particular language's speakers and readers!

I'm going to go with the second definition Alex! "well grounded or justifiable: being at once relevant and meaningful" as being clearly the intended and most accurate application of the word in this context, specifically employed to in fact to avoid a more inherently judgemental term such as "good" or "acceptable".

Valid, adj.
: having legal efficacy or force; especially : executed with the proper legal authority and formalities valid contract>
2
a : well-grounded or justifiable : being at once relevant and meaningful valid theory> b : logically correct valid argument> <valid inference>

3
: appropriate to the end in view : effective valid methods>

4
of a taxon : conforming to accepted principles of sound biological classification

— va·lid·i·ty \və-ˈli-də-tē, va-\ noun
— val·id·ly \ˈva-ləd-lē\ adverb

Rather than your tortured attempt to synonymise it with "acceptable or good" to accomodate your own preconceptions.
