Source of Terrorism and Hatred

We need to handle our violence problems, and I am not an expert, but I would tackle it from several angles. In this post, I will just write about one problem we must address - the source of the violence. Where is the source of hatred toward gays coming from? It is obvious to me: the Abrahamic holy books.
Think about it - can you come up with another source for both the personal mass violence toward gays and the violent rules of countries that are based on a religion?

I do not see why this is not obvious to everyone. These holy books teach that being gay is sinful, when there is nothing wrong with being gay. Christians are taught to say, "We love the sinner but hate the sin." Well, calling them a sinner is archaic and incorrect, and hateful. Christians will avoid being called discriminatory by saying, "I will not judge, but God will judge them." That sentence is an avoidance technique, and also says that your god has an unfair system at work.

There are calls for mass killings in the Bible, and evangelicals to this day still encourage the killing of homosexuals. Most of you do not know that approximately the same day that the Orlando night club members were attacked a white man had a huge arsenal and was headed for the Pride festival in Los Angeles. Fortunately, he was caught and arrested. I will assume he was not Muslim, as we have had many Christian attacks on homosexuals and other minorities.

I wonder when people will admit that the Abrahamic holy books are dangerous and seriously out of date. Either demand that your books be heavily revised, taking out all prejudice toward homosexuals, women, minorities, children and animals, and all violence (it will leave a thin, but lovely book), or ditch such dangerous books all together, as they are the basis for violent people and violent countries.

Due to our system of religious freedom, people feel they cannot criticize religions, but even though religions help a lot of people, the harm they cause is immense and world-wide. We have to examine and amend religious beliefs and stop ignoring what is clearly written in the books. Criticism is not persecution. You are still free to believe whatever you want, but at least be honest about what is written in your religious books and what is being taught in many of the religious places of worship.
