Also, I for one still think of a clone as more or less a replica of someone. Which could also be regarded as taking away something that is unique about a person. But as pointed out, a clone could never be an exact replica, and this fear is therefore unfounded.
Yes, that's mostly in line with my idle speculations on the matter: the thought that someone else could make one's
doppelgänger is disturbing. It suggests that one's uniqueness can perhaps be threatened. It also suggests that the visual dimension is a primary factor because the thought of a "clone" who only thinks, but does not look, as I do is, at least to me, somewhat less disturbing than the converse.
On the other hand, identical twins seem unperturbed by all of this, perhaps because they usually grow up together and are therefore totally at ease with a complete and living likeness of themselves.
But I'm only guessing here.
