"That doesn't demand any consideration of what real world laws are, should be, or what the rest of society may think."
Ah, thanks heavens for a little Voltaire! I think you may be shouting into the wind with society as a whole if you intend to lean on Kants Categorical Imperative, however, as no one thinks like that anymore. it's all "me, me, me" and "I want" or "I don't like". Glance down this forum; "I want to castrate him", "I want to ban facebook", "I don't like it, so you can't have it.". People just don't realise that if they got their way, so would everyone else and before you know it, we're all screwed out of something we value or want.
If you aren't willing for the ethical rule you claim to be following to be applied equally to everyone - including you - then that rule is not a valid moral rule. You can't claim that something is a valid moral rule and make an exception for yourselves, or arbitrarily for others of your choice; those who agree with you, for instance.
Nope, the crowd says non-consequentialism rules, and as we all know in this day and age, the crowd is loud....I mean right...sorry.
