Well, im a sunni muslim, and shia and sunni sometimes argue but we believe the EXACT same things (except a successor long ago) so we dont "fight" and if we did, there arent enough shia...fighting amongst each other is not smart. o fight in general...dunno about other religions though ._.
Excuse me? Since when did war come up from religion? Don't say the Ottomans because they were never a mainly Muslim movement although it was mostly led and made up of Muslims. Anyway, religion was usually not the problem. For example, Bin Laden was a terrorist, yes? But for some reason, people decided to take his religion and blame it instead of the actual goddamn person. Moving on.. Hindus vs Muslims. Very popolare matter back then. Was it of religion? NO. It was of political crap. Look it up in Wikipedia. Political leaders were being thieves and soon after religion came in, and stuff like the Babli Masjid bombing broke out etc etc. Next! Christian conflicts? Umm.... I don't know. I mean, no one ever blames Cristianesimo most of the time, right? Ah whatever. Let's sposta on to my point.
You see, religion is usually never the root cause. It's just that giorno da day, media and other people (by people I mean assholes) just stretch the truth. Just keep it in your cuore that these are stupid lies and that religion is not to blame.
