Whilst I disapprove of this man's actions, the illogical and quite frankly, imbecilic nature of religion is neatly summed up in the article, which states, “... Islam teaches its followers to avoid pig meat as it makes them impure and unclean...”
I realise that a debate about why Muslims (and Jews) find all products derived from pigs to be abhorrent is outside the scope of this thread but I cannot help but roll my eyes when I read such things. Coming into physical contact with a particular meat does not and cannot make one 'impure' (presumably this means 'spiritually impure' which is an essentially meaningless term) nor 'unclean' (again, if we're talking 'spiritually', it's essentially meaningless).
Apart from ruin some chap's shoes, what this fat tub of lard did was insult someone's ideas. Hardly an offence that warrants incarceration.
