Student Arrested and Fined for Calling Horse "Gay"

From the Oxford Cherwell on-line, via Melanie Phillips [h/t to MA]:

Brown and his friends ...had emerged from the Cellar Bar and were surprised to encounter two mounted policemen.

Brown inquired, “How do you feel about your horse being gay?” of one of the policemen, stating that his colleague’s was clearly not gay. After repeated comments on the sexuality of his horse, and despite warnings from the policeman about his behaviour, Brown’s offer of an apology to the horse was rejected and he was handcuffed and taken by the officers to the police station.

The idea of apologizing to a horse amuses me. Other than that, do you think maybe Brown is homophobic when sober?
