How did you become an atheist?

[Edwardo Piet]

I don't even know what got into me. How could I be so rude to everyone and thinking so much of myself when it's pretty clear that not even a soul agrees with me. You can't be right when everyone's telling you you're wrong, right?

... I'm such a dumbass. Really. I should just leave in disgrace and never come back again.

Agree with everything but the bolded part. And I'm neutral in regards to the underlined part.

And I know that you know that the bolded part is untrue. Despite the fact I don't think you're 'extremely intelligent' you're far from a dumbass and too intelligent to not be aware that of course it is possible to be right when everyone is telling you that you are wrong, and you are not a dumbass, and you know you're not.

As for the underlined part... only leave if you want to... people may or may not be mostly better off without you but even if they're better off without you, it's your choice to stay or go and it may be better for you if you stay (then again the tantrums you are having here might suggest it's better for you if you leave, but it's still your choice). I don't dislike everything you post, just a lot of what you post... but that's just my opinion and, again, it's entirely up to you if you go or stay.

A break might do you some good though, but, again, it's up to you.
