Should transgender people tell their sexual partners they are transgender?

[Earth]

Assuming they're pre-op, then yes.

People don't become transgender or transsexual on a whim.

Presumably not. It scarcely follows, however, that their decision is a morally-appropriate one.

Do you want to offer some sort of rational justification, or just keep spouting crap?

[Earth]

"[R]ational justification" for what? My assessment that it's immoral?

Yeah.

Like my opposition to mass murder and torture, it is grounded squarely in intuition.

Obviously. It's funny you use those examples in this.

Because I doubt any of our readers subscribe to the same general principles, I see no benefit in laying them out.

Essentially because you have nothing noteworthy to respond.

[Earth]

All moral norms are grounded in intuition. Is it your position that the field of morality itself should be abandoned?

My position is that it's entirely ridiculous to base transsexualism on morality. It tends to underscore other ridiculous presumptions.

The point is that the feelings of "moral disgust" and "taste-related disgust," though clear to the human mind, cannot be described.

Of course they can be described. Moral positions are not inscribed within the mind such that they are inherent to the person holding them. You can describe both what you feel when confronted, and why you hold a certain view. You just choose not to describe why you hold a "moral" position that pertains to transsexualism. You could offer reasons why you find it "distasteful" or 'wrong', but instead you treat this as a trite philosophical problem. Pure sophistry.
