As an atheist, what angers you?

When some asshole I've taken the time to patiently explain what evolution is and is not, following their initial batshit crazy claim about what science supposedly "really" is, and they reply with something like, "From a plant you get a plant, from a donkey you get a donkey and from a human being you get a human being."

STOP THE PRESSES! TELL THE ENTIRE SCIENTIFIC COMMUNITY THEY'VE BEEN GETTING IT WRONG ALL THIS TIME!

The thing that pisses me off about this kind of "objection" is that evolution agrees with them. From a (general description) you get a (same general description). They are obviously under the delusion that evolution states something different. Of course the offspring is going to be extremely similar to the parents. But the description we give a thing such as "a donkey" is entirely arbitrary, so to say it's "the same" is a kind of equivocation fallacy. It's not identical, it's just extremely similar. You can't use labels to halt incremental change.

They just can't grasp the timescales involved, I suppose. It's these continual objections to positions no one actually holds that is annoying.
