okay first of all I'm not a Muslim [Spirituality & Religion]

What religion do you believe in? And what's everything?

i am nihilistic in my worldview and dont believe in any fairy tales or religious texts

Well i don't think religions teach us hate those holy books are written by people so there are a lot of conflicts and about that people or books would say anything its up to you to decide what's wrong and what's right :)

fact is i would most likely executed if i openly spoke my beliefs many country that represent millions of muslims. now tell me are all those muslims wrong ?

No you won't you can be in a Muslim country and follow your religion you'll meet stiffs everywhere :) and those terrorists would do that to you for sure but that's what they do they kill people even if you were Muslim they'd kill you for not joining their forces or for some other bullshit

iran and saudi arabia two of the most important muslim countries do not tolerate atheism

I have many friends living in saudi and following their own beliefs that's mostly Hinduism and Christianity they were never bugged by any Muslims for that

hinduism or christianity isnt that much of a problem... atheists are threatened by death in a lot of countries and are openly discrimintated in many countries.

no race/religion/people is as much hated world wide as astheists are.. well jews maybe..

So that happens everywhere not just in Muslim countries and read history which religion failed to kill an atheist?

there is a difference between religions where people dont like you and mistrust you as is the case for many christians and religiosn that actively speak out fatwas and encourage people to kill you...
