With all due respect, I think you're being a bit silly and naive, walaal. If you don't practice Islam then that's entirely your business and no one genuinely cares except maybe any relations you live with.
What ruffles people's feathers and I feel you're wasting your time with is trying to get people to be accepting of atheistic beliefs and thinking. It's a very religious society, for better or worse, so your recourse as someone who wants to remain within the culture is to either be that quiet adeer who doesn't go to the masjid, drinks khamr and no one really bothers because if he is an atheist he keeps it to himself, or be vocal and in people's faces about your disbelief where, I'm sorry, you're going to get some ugly reactions indeed.
