I object to the word "retard" as a term of abuse.

I don't object to the flashing of thongs (unless the relevant area is in itself unsightly).

I don't object to other people losing their virginity at the age of 14 - I wish I had lost mine at that age (ah those wasted few years...)!

And I don't promulgate different behavioural rules for the different genders.

I do object to the sort of ignorance and offensiveness described by the OP.
