That's the main issue. Not offended by gay jokes in the slightest, but if you're gonna make jokes about him, at least think up some original and funny ones rather than the ones used for the past year.
He's a player for Newcastle United and more importantly another human being. The "gay jokes" shouldn't stand, period. All it promotes is your own uncomfortableness with homosexuality and intense ignorance. Anyone who makes a gay joke at Xisco's expense needs to take a close look at themselves and try and figure out why they even feel the need.
