If you rewind, do you think there was a "religion of the Arabs" without compulsion? Before Arabic lands were in the rearview mirror? After some years doing the grassroots movement thing to gain numbers, people were pressured and bullied by ultimatums that almost always had "lest you become Muslims" attached.
Homeland or foreign, convert or die wasn't always the ultimatum, you could also become a submissive second-class citizen, with more than just taxes taken (could decide all your wealth and crops needed forfeiture), or flee...if Christian or Jewish at least. You don't need slaughtertor torture to punch the "this is compulsion" ticket.
The main point is what is Islam and who is confused about what Islam really is. It's redirection if we keep focusing in on other groups to make things seem not so bad. How awful or wonderful other groups have been doesn't decide what are unfair misconceptions of Islam.
Christianity and especially Catholicism has a dark history too...of how Christianity 'grew.' Looking back in time, Gnosticism was/is thought to be the earliest form of Christianity, but many were murdered in favor of the brand of Christianity we see today. The history of the RCC is VERY violent and grim.
But, the world is more forgiving with Christianity, than with Islam. While Christians are not currently forming violent coalitions to take over various regions of the world like ISIS, Christianity still tries to oppress groups that the Bible depicts as 'sinners.' Homosexuals come to mind, albeit the tide is turning. In the RCC, women are still not permitted to become priests. Christians in the U.S. were largely supportive of slavery, once upon a time. And in some Christian sects, it's still permissible to hit one's wife. (as sanctioned by the Bible) The U.S. is a very violent country (regardless of the reasons stemming from religion), and our justice system isn't exactly humane, when we look at the male prisons, and how rape and AIDS is on the rise within them. We look at Sharia Law and think that we could never govern in such a manner....meanwhile, if someone steals here, sure his hands aren't sliced off, but instead we throw him into a prison system where he will be left to fend for himself ...and the odds of being raped and assaulted on a weekly basis, are pretty high. Is that more/less humane? The truth is, people can get used to just about anything if it is passed off as legal. And America doesn't say much.
This is a human problem, not necessarily a religious one. Humankind has a beautiful compassionate side, and yet a very dark, depraved side that seems to be obsessed with human punishment. It also seems to be focused on one group is ''above'' another group...also, not a religious thing. Now, if you live in a part of the world where you are taught that your religion can and does govern your everyday life...you might find it normal, because that is all you know. When I read about stoning of adulterers in the middle east, it is mind boggling how they can still be stuck 2000 years in the past. But, then I look at the US, and while we appear more civilized...our prison system is anything but. (in many cases, there are prison that have rehabilitative programs in place)
Yes, there are serious issues when it comes to Islam but there are issues throughout the world ...that underscore a human problem, not merely a religious one.
