A religion is not an abstract concept. It is a living, changing and evolving concept because at any given time it is a community of believers. Christianity in the Middle Ages was a far less tolerant community than it is today. The reason it is now more tolerant is largely because the experience of the Wars of Religion, the Enlightenment and the Post-Modern experience have radically changed the views of the people who profess it.
Islam today is going through violent and disruptive change. There are people preaching violence, and there are a lot of them. It is possible to read the Qur'an and justify this violence in it - the Salafists say that the Medinan surahs should take precedence over the Meccan surahs because they were written later, and the Medinan surahs have the problematic language that justifies killing non-believers.
While other religions can be interpreted to support violence, at the present it is Islam that IS being interpreted this way, and by a significant number of adherents. To attempt to equate religions is to wilfully ignore the reality in which we live.
Hmmm....I guess you're right. I read through the other responses. And you explained my flaws better than I could have. I was describing them as a static concept. Ignore the human elements and what you have is strictly the words on the page and the messages behind them. With people's interactions, I would undoubtedly agree that Islam is more violent than the other major religions. It's pretty clear. So what it looks like to me is a difference of how you wish to perceive religion. I want to hold a religion to its ideals, to say that this religion is essentially peaceful because that's what these words mean to me. But you're right in saying that is ignoring the reality because the reality is that that is not everyone's view and in reality, majority rules.
