It's not so much of a secret, but it's worth stating bluntly.
I dislike New Atheists. In fact, I dislike self-identified atheists in general. There are exceptions, but my universal experience is that their arguments are bad, their attitudes are obnoxious, and their displayed confidence manages to so outstrip the evidence that it's easy to ignore all the signs that it's also feigned. I can get along with the irreligious and agnostics at times - and yes, even some atheists - but most of the time they just get on my nerves.
That's not the secret.
The secret is that I've got a similar attitude towards quite a lot of Christians too.
Obviously, I like many Christians, and much Christian thought. I better, since I'm Catholic, with all my failings. And some who I used to dislike, I've changed my mind about - I used to have that culturally inculcated fury at YECs, and that's gone now, without changing my views on creation or evolution in any meaningful way. Obviously I dislike SJW Christians, who I view as a kind of cancer which manages to befoul everything they get their hands on.
But other kinds of Christians just bug me, and this probably is because I'm a misanthrope more than anything. I do not like the tendency towards drama, with people tearfully pleading for prayers owing to their dark night of the soul moments, which always treats their faith as something they have zero responsibility for and which teeters on the brink whenever they have shitty experiences. I do not like the tendency towards me-tooisms, where every faddish or prominent 'cause' is a signal to rush in and make it a matter of urgent Christian concern. I do not like the moral cowardice at being perpetually afraid of being called racist, or sexist, or homophobic, or anti-scientific, to the point where they not only will drop positions or doctrines which earn secular ire, but will prove their purity by playing witch hunter at anyone accused of being such things. I dislike the Christian addiction to self-mortification without justice, and apology without wrongdoing.
Granted, I'm not exactly the most pleasant guy around either. But the West has rotted on Christianity's watch. At least some Christians-in-name played a role in that, and my dislike of New Atheism does not blind me to that.
