While I understand the context of [T]/[t], I think we should get rid of it, and as a whole recognise that trans men are men and trans women are women.
There is no need, if one insists on a binary classification, to specify, and you certainly can’t capture all transpeople with a single tag.
Remove it from the sidebar, is my vote, or get as specific as you need to be.

I think the main purpose of the [T]/[t] tag is for transgender transformations. You know, man to woman and vice versa. I highly doubt that it’s based around actual sexual identity, as I can’t see many applications where that could be used in an erotic context.
