copts are allowed to eat pork. just it's never been very popular, it's a bit like eating cheap sausages when u could have a nice steak instead, it was never trendy.
and in egypt, the government used the swine flu scare to kill lots of pigs. the Christians that were living off that trade were poor people whose pigs lived on eating garbage, so there were people in government happy to put them out of business.
it got rid of some pigs and hurt the Christians at the same time, so it was an efficient way to carry out government business.
as for chicken, if u eat it, u should insist on free-range chicken, or at least chicken that has plenty of room to move about the barn. it's keeping chickens in ridiculously overcrowded conditions that makes them aggressive, they are not naturally like that.
actually the same applies to humans (anyone been to london/paris/any other big city?!)
ethiopians and eritreans don't eat pork, whatever their religion (unless they are doing it secretly when granny is not looking). we had ham in my previous coptic church once, and my teenage friend was arguing with his mum about eating it. she didn't let him.
personally, i do eat meat, but i prefer some nice beans...
