The reason behind the young gentlemen's suicide is unknown to my knowledge. Perhaps he was fearful of consequence - there are many, many cases all over the world whereby people live in abject fear of reprisal, over things like their sexuality, or being with a partner who isn't from 'their' culture or ethnic background.
To emphasize again: the motive for his suicide is as far as I know, unknown. Therefore one can only look at the possible motives. If that's considered by some people to be personal attack on say, Islam, or their religious beleifs, then that's too bad in my opinion; there's a young lad here who's ended his own life..what a waste. Now, let's get on with the business of establishing the reasons why he felt compelled to do it.
