What's the discrimination?
Genuinely. What discrimination?
Not allowed to marry? Nope, not that.
Not allowed to have a job? Nope. Pip Bunce has done very well, thank you very much, as has Debbie Hayton and Robin White. All pretty successful, I'd say.
Not allowed to use public transport, or told to sit in particular seats? Nope, not happening, thank goodness.
Not allowed to vote? Ah, no.
Not allowed to be MPs? Or Doctors? Or lawyers? Or teachers? Nope, see Bunce and Hayton and White.
Discrimination - being asked to play sports against members of their own sex, being asked to use facilities intended for their own sex, being asked NOT to use facilities intended for the opposite sex.
Have I missed anything?
