Biblical Inerrancy - mandatory to be Christian?

[CleanShavenJesus]

All atheists are moral relativists
All moral relativists are nihilists
All atheists are nihilists

How does this logic break down? How is an atheist not a moral relativist? How is a moral relativist not a nihilist?

All humans are either male or female
All males have a penis
All humans have a penis

^ That doesn't seem to make much sense, does it? Neither does your conclusion. Not shockingly, might I add.

I'll say you're correct about atheists being moral relativists, hence the correct line in my comparison "all humans are either male or female". But then you go ahead and say all moral relativists are nihilists? How the hell are all moral relativists nihilists? Where are you even getting that from? Then, from that, you jump to say all atheists are nihilists. All atheists are nihilists just as every human on Earth has a penis.

Actually, if I were to make my own comparison parallel to yours, it would actually go like this:

All humans are either male or female
All males have a vagina
All humans have a vagina

....because the statement "all moral relativists are nihilists" is as incorrect as "all males have a vagina". Prove to me that all moral relativists are nihilists.
