I don't see any point in arguing over how far we can go in disagreement over belief/nonbelief.
Hey, each one of us is free to go as far as we like. When a Christian mocks the unbelievers, I feel they often think they deserve a pass because it's in the name of God and any retaliatory remarks some of these Christians receive make them cry out "UNFAIR, HATRED!" The unbeliever and the Christian both think they are doing the other a service by "mocking" the other. So those who can't take the criticism should not dish it out.
And come on people. If an educated adult were to seriously believe the Santa Claus story, would we not mock him? Flying reindeer? All the houses around the world in one night? So if a person wants to come off as firm in their belief in some crazy things like the virgin birth or the worldwide flood of a few thousand years ago, they are taking on the burden of being criticized for that. Their opinion demands that they educate themselves about it before insisting upon such a view.
I tend to agree with those that think Dawkins' attitude is a bit extreme, but he makes a living out of that. I am for HIM doing what he does because people can seek him out or avoid him. I will mock extreme beliefs on this forum, but I won't necessarily mock sincere believers in person when they seem to be reasonable people otherwise. That's because I see this as an appropriate place for that.
But I also see times when the believer chooses to pick the fight in person- state their silly claim and insist that arguing with it is hatred or ignorance.
Now, having come from the Jehovah's Witnesses, if I have a conversation with a Christian and they go to church or express their general agreement with the words accredited to Jesus of the Bible, and they are all about love and peace and harmony and they think that their Christianity contributes to such, I see no need to attack or mock them for such thoughts....as long as they don't insist I see it their way or they don't belittle those that don't see it their way.
