The punchline to the joke that is New Atheism. Someone who posts to r/atheism, usually submitting generic quotes about science, unwarranted fallacious Facebook arguments, and "memes" about God not being real. Thinks science and religion are polar opposites. Tends to mistake European nativist propaganda for atheist propaganda due to their hatred of Muslims. Usually openly bigoted against religious people.

Jim is a total ratheist. He said that all religious scientists are secretly atheists.
Ratheists have successfully formed a community where outright bigotry is the norm.
Sam Harris said religion is worse than rape. Ratheists love him for it.

As "rather" indicates a preference between two things, "rathest" indicates a preference among 3 or more things. Most rather.

Between Italy and Spain, I'd rather travel to Spain, but out of all places in the world, I'd rathest visit Greece.
