"God doesn't Exist"- Claim or Conclusion

[Homeless Nutter]

1: That God(s) exist is true.
[...]

2: What can be asserted without evidence, can be dismissed without evidence.

Someone who considers proposition 1 true is a theist.

And therefore - a child, a gullible moron, a nutjob, or a liar, since that's how we categorize those, who claim to believe unevidenced propositions, based solely on magical thinking, motivated reasoning, as well as arguments from popularity and authority.

What do you call someone who considers proposition 2 true?

Uhm... Whatever his/her name is?...
