I do not know what Caster Semenya’s sexual orientation is. What I do know is that she is constitutionally entitled to decide how she wants to be, in terms of her sexual identity and her choice of sexual practices so long as this does not violate the rights of others.  We are speaking of a young woman who has had traumatic experiences because her sexuality was questioned in the course of her athletic career.  A comedian is a public figure and if that person is to do more than make people laugh, especially if s/he is a satirist there must be some sense of responsibility and respect towards other human beings especially someone who is vulnerable.  And this is especially so if Caster Semenya has chosen a sexual identity that deviates form heteronormativity.  We are living through a period of repeated ‘corrective rapes’.   We are entitled to expect that all public figures should take steps to combat this scourge and even if their job is humour, to defend constitutionalism, and individual identities and choices.
