I'm from Brazil ! I have never participated in an atheism forum! I hope to learn more about atheism! Can this forum also learn about skepticism?
Ricardo...Ricardito...Are you a religious person?
I ask because when you start a sentence with: "a theistic friend told me he has two arguments against atheism..."--It's like when I ask: "Is marijuana bad for you? I have "a friend" who wants to know. ... 
So, are you a religious person? You sound like one.
I was thinking the same thing. But I'll wait for Ricardo to own up to being a religious person or stop looking so much like an "undercover theist". 
Ricardo, Magdalena and I are skeptical you are an atheist. There's nothing wrong with being a theist -- we have theists who are regular members of this forum -- what isn't cool is pretending to be an atheist when in fact you are a believer. Are you really an atheist?
I am an atheist agnostic, I think you have the impression that I am a theist because I have no prejudice against theists even though many theists have prejudice against me for being an atheist agnostic! and do you suffer prejudice from theists? what's your reaction? 
Ok, fair enough. I'll give you the benefit of the doubt.
I'm still pretty much a closet atheist, only close friends and family know I think the way I do. I have theistic family members, some very religious and others less so, and theistic friends as well. Religion is just not something we really talk about.
As for the preconceived notions some people have about me because of my lack of belief in any gods, I just ignore them. At first, it would make me very angry but now it's just not worth my time and energy.
