Some people were responding to a forum post by a person on declawing community cats. In the first place, besides the fact that one should never declaw an outdoor cat because you take away their only defense mechanism, declawing is something that is actually illegal in some countries and considered to be mutilation in others :-
Declawing : what you need to know
The European Convention for the Protection of Pet Animals outlawed it. Section 5 of the United Kingdom's Animal Welfare Act prohibits mutilation, which involves interfering with the 'sensitive bone structure' of the animal, excepting medical reasons.
Declawing is something to benefit owners - it rarely does anything for the cat. Some owner may decide they would rather give away or kill their cat then have it scratch their furniture - in which case I know some vets in Singapore do consider this as an option. Of course this may not stop the person from giving their cat away anyway after that (and we have had some declawed cats on our adoption board in the past).
