Farm Family - I hope nobody is offended by this. I understand that homosexuality does not necessarily imply transgenderism or transvestitism. I thought of the pun after seeing a certain movie this summer that inspired it.
Let's not have a big discussion about it (though I am happy to if you like), but yes, I do find this rather offensive (as well as your wording "does not necessarily imply" - it does not imply it at all).
