Have you discussed any difficult subjects with them? Suicide bombing, Jihad?
yes , just recenently like i said. suicide bombings, but that is not a difficult topic, the same guy had alot more trouble with the topic of evolution
but suicude bombing was a topic recently , he claimed suicide bombers are not moslems. what they do contradicts Islam. It does not contradict Islam according to the radicals. he said well they are wrong and they know nothing about Islam if they think such things are justified. and he came up with the usual defence i know from them by telling me how Islam teaches that even killing one innocent person is like killing the whole humanity bla bla. and i said , yeah i know that this is what you believe, but that is not what they believe and they use the part that teaches that its ok to kill those that invade your country. and he went on to other peacefull pasages.. i told him that it all comes down to cherry picking stuff they find usefull. like all religious people do. they pick the parts they like and ignore the rest. and just because he does not agree with it, doesn't mean that they are indeed not Moslems. who's to judge who is and who is not a real moslem. and so on. he never was offended, never got angry, we ended up agreeing that the terrorists abuse a religion to get their means.
but its hard to offend him any way , and he is the most religious one. i told him his god does not exist and is merely a construct by humans. ha you will see was his answer. and we are still friends and respect eachother as humans.
and no i do not think all moslems are like the ones i know, i several times said that they are the most modern ones i have ever seen. i fully know that many are far less modern, and dont see their religion so relaxed and as totaly peacefull. and i know there are huge numbers of radical moslems willing to blow up innocent people. they are a real problem and need to be destroyed. but they are not Islam itself. they are not the majority of moslems.
i come from a part of the world were most people believe in a religion that i find absolutely disgusting. a monster god that kills all live on the planet except for one family and 2 of every animal. but heck , those people around me, pass that as a story for children and those same people see so much moral value in their religion and strangely construed a peacefull religion out of it and are easy to be living with.
maybe its just that i am used to people that can take the most disgusting and appaling stories and still cherry pick a peacefull way of live out of it. i have seen Christians doing it, i have seen Moslems doing it, i am used to that acrobatics

better this way than the way fanatics cherry pick
