I think that there's some terrible stuff in the old testament of the bible. It can be incredibly misogynistic, anti-gay, among a lot of other problems (such as barring people from going to temple because they're disabled, considering bacon an abomination before The Lord, and The Lord commanding His People to commit total genocide including salting the earth and poisoning the wells of His enemies).
Sane faiths have tried to deal with the evil in the old testament. They've had some of the best minds in history working on these problems for centuries, and they've literally written thousands of pages of text in philosophy, logic, and theology to explain away those evil acts and create a logical and cohesive morality based on those texts. Some believe in that theology, and others think it's just a steaming pile of apologetics.
Now, these days, most Jews are pretty rational about this stuff. Most of them don't run around beating the drum of war and calling for the genocide of those that are dissimilar to them. There are a few, but as a group, I tend to give the Jews a pass. It also helps that they don't annoy me by knocking on my door and trying to get me to convert to their flavor of God. I cannot overstate how much their non-proselytizing attitude helps their cause in my book. It's quite a thing that they haven't killed thousands or millions of people trying to convert people by the sword like Christianity and Islam is wont to do. I digress...
The point is, that the majority of Christians, Muslims, and other faiths based off of the deeply flawed books of the God of Abraham are decent people. Most of them do not believe that it is okay to kill in the name of God. Most of them do not think it is okay to convert people by the point of the sword (or by the mussel of the assault rifle). But there are outliers. Fanatics. Fundamentalists that reject the centuries of theology that mitigates the evil in those books. People that take it literally when the book says that a woman who cheats on her husband (or gets raped) is to be stoned to death. People that take it literally when the book says that oral or anal sex is an abomination and that those that practice those acts are an abomination and should be stoned to death... actually, truth be told, very few people take that part literally, unless the acts are between a man and a man, or between a woman and a woman. You don't really see those people screaming to murder their neighbors who had sex during the wife's period, as it calls for in Leviticus.
It's the fundamentalism that's the problem. It's the zealotry, the xenophobia that's the problem. But Christians don't really speak out against the fringe crazies that rattle their swords and call for a war against gay people. Christians don't really try to quell the extreme fringe among them that say that a woman must always defer to her husband's better judgement, that she must always be obedient to him, and that he can hit her if she doesn't behave. Christians just put up with the radical fringe, not wanting to make themselves a target, letting the Westboro Baptist Churches of the world get away with murder, sometimes literally. Of course, Muslims have the same problems, the same tendencies, the same sorts of xenophobic douchebags in their midst. They don't really do or say anything about them either.
The problem here is hypocrisy. People won't confront the crazies in their own communities. Yet they expect the people that live half way across the world to be confronting the crazies in their religion. Now maybe if we focused on fixing ourselves, in excising the cancer of fundamentalism from the public arena, made it abundantly clear that decent people in our society WILL NOT tolerate the xenophobic bullshit, the misogynistic bullshit, or the anti-gay bullshit of the American Taliban, maybe then we'll have something positive to say to the Islamic world. Maybe then we can show them a better way. But until we've done that ourselves, well, you know what they say about people in glass houses throwing stones.
