The fact is, you could (especially since you're a deontologist) decide that any old thing is morally wrong... Perhaps your declarations of what is or is not morally wrong make sense to you, but to other people, they just look arbitrary.

This is actually not an accusation I've had leveled at me before. Consequentialists tend to object to how rigidly I define moral rules, not which ones are on my list. I'm pretty sure this is a strawman.

now you're declaring that anyone who disagrees with you is a Bad Person, and not even straightforwardly: you're making insinuations about their character ("sketchy").

This is just an uncharitable misreading of me. I don't think I'll engage you in particular any further on this subject unless you produce a dramatically better understanding of my position.
