Intolerance to differences

AMU professor suspended for being homosexual, reads a headline in Times of India's Feb 18, 2009 paper. It's shocking. But what's more shocking is the manner in which S.R Siras's sexual preferences were 'exposed'.
The professor, who was due for retirement, was reportedly caught on camera having consensual sex with a rickshaw puller in his house on the campus. And this whole feat was achieved by his students, in collusion with a local television channel. At least, the report in one parts says the students engineered the thing and another part says a local channel was involved.
What is it that makes us so narrow-minded and intolerant? Students, who are supposed to be enlightened by education and open to ideas, go to the length of entering somebody's private space and disrobing him in public.
How does it matter what somebody does behind closed doors as long as it not something that hurts another? Are we trying to play moral cop for all the wrong things? It's understandable if he was harassing any of his students for sexual favours or indulging in 'gross misconduct (the ground on which he was suspended) in the college.
But this! Is shocking to say the least.
