I think "hate" is a pretty hard word. I don't hate people for their beliefes, not until they harm someone because of it. But yes, I would describe myself as a Dawkins kind of Atheist (actually I don't really like Dawkins, there are some German humanists/atheists, that I prefer).
So why am I "militant"? Because I don't think, that religion is something good for the society, as more fundamentalist a religious person is as worse it is. That's the reason I support atheistic/humanistic activities.
The examples of those most vigorous proponents of their religion - namely the saints - not-with-standing. The problem in religious history (for Christianity, anyway) has not been following the faith too much, but not taking it far enough.
It was economic greed and a lust for power that drove the political abuses of the middle ages which paid only lip-service to Christianity. It was an overgrown set of uncontrollable and animal passions (condemned by real Christianity) that led / leads to the violent militantism you so rightly condemn.
And look - atheists themselves have commited the same attrocities and more in the name of zealous passions. The Communist holocaust of religious believers in the USSR stands as a stark evidence that the removal of religion is not the balm the New Atheists think that it is.
Far from it - if you remove the metaphysical beliefs undergirding Christian ethics, eventually you LOSE those ethics (society-wise) as well. The sense of the unique value of the individual, the command to love our enemies - these depend on Christian metaphysics.
People - the same passionate, greedy, powerhungry people who blackened the name of Christ with their actions in the past - will not take long to take the new, subjective metaphysics of New Atheism as their calling card. In it, they no longer owe lip service to things like valuing life and love, but may freely extend the hand of their greed as they see fit.
Mark my words well: the death of religion will return this world to chaos and inaugurate a hell on earth as man destroys man on the assumption that no ultimate moral will exists and no ultimate accountability presides in love in the world.
Though I respect the neo-humanist critique of the damage religious abuse can cause, I think the over-reaction of the New Atheists throws out the baby with the bathwater.
I'd also be interested in hearing your syllogism written out. What major premise do you use to justify your position. Your minor premise is that Christians (or religions) haven't followed their teachings at all times. What major premise do you use to, then, reach the conclusion "Christianity (or religion) is false." I've never seen a functional major premise linking those two parts of the syllogism.
In Christ,
