And when one points out what I pointed out, note how a self-described liberal Christian responds in pretty much the the same way as a conservative Christian does, replete with daft generalisations about atheists.
I don't know where you're getting your generalisations from, but most atheists would love to have more liberal Christians around. It is certainly more preferable to conservative Christianity, but it is still nonetheless a baseless belief, so it would not exactly stop the debate on the validity of it. Debating the validity of an idea is not hostility, either.
I just think it's worth reminding ourselves every now and again that liberal Christians aren't so different in some respects from the conservative Christians they decry. You each think the other cherry-picks, for one.
