I think that petunia's post above is an example of a reasonable voice, and that someone saying that transexuals should not have the same rights in law as others would be transphobic, as would someone shouting at transexuals in the street, or denying them employment or promotion on the grounds of their sexuality, with the caveats described below. I have not seen (or do not remember seeing) examples of transphobia on this thread.
I do not think that the suggestion that non-transitioned male-born people should not be allowed to be in intimate contact with vulnerable women who choose not to be in such contact is transphobic. I feel that this is a relatively niche situation that could easily be enshrined in law, and that the situations it would cover are relatively few. I don't understand why, if a transwoman sees herself as genuinely female, she won't understand the real fear that someone who has been raped by a man with a penis is going to have of someone else with a penis being assigned to examine her internally.
It is, to me, perfectly obvious why this would be traumatic, and I would go as far as to say that anyone (of any gender) who does not understand this is not an appropriate person to do it.
I expect you to disagree with me, which is fine, but please try not to resort to cheap insults or dismissive phrases, as I struggle to want to engage with people on that level.
