It is just as stupid to make jokes/remarks about 'hetties' as it is about 'homos'.
Although the predominance of 'hetties' would ensure that any such comments are really just gnats at elephants; comments about 'homos' have more weight behind them.
It is surprising just how many 'non believers' will turn to the bumper book of fairy tales as authority for their prejudice.
In the same way that society is slowly coming round to the fact that racial discrimination is wrong, so hopefully, in time, it will come to accept that discrimination on the grounds of sexual orientation is wrong.
By all means, hate me because I'm a vain, shallow, capricious, argumentative, etc. but please not because I bat for the other team.
