You are not transphobic if...
... you as a cis-lesbian don't like shemales or preoperative NGS women (because you don't like penises)
... you as a cis-gay don't like hefemales or preoperative NGS men (because you don't like vaginas)
... you as a heterosexual cis man don't like shemales or preoperative NGS women (because you don't like penises)
... you as a heterosexual cis woman don't like hefemales or preoperative NGS men (because you don't like vaginas)
Nobody has the right to dictate others their sexual preferences!
Nobody has the right to convince others to feel guilty just because they don't like male or female genitals!
Nobody has the right to manipulate others in their sexuality in such a way that they sleep against their will with a person whose genitals they don't like, just to avoid being called transphobic!
Preferences are preferences and not transphobia or discrimination!
