If I'm an anarchist, it means I'm against all governments, it doesn't mean I'm an archist when it comes to republicanism but an anarchist when it fascism, it means I believe in NO GOVERNMENT.
If I'm apolitical, it means I'm NOT political, not I'm political when it comes to some countries and not to others.
If you're an Atheist, it means A-THEOS ... NO GOD(S), none, 0 zilch. Look it up. It means you believe there ARE NO GODS.
If you're Agnostic, it means you are without knowledge, when it comes to Gods ... you DON'T KNOW, you don't disbelieve .... you don't believe.
If you're a Theist, you believe there IS at least 1 God.
