Ex-theists are often like ex-smokers, sanctimonious and insufferable.

[Dystopia]

Religions are all poisonous. They all corrupt thinking. They all depend on people not thinking clearly, and so they oppose clear thinking.

And that should be opposed. Getting people to be unreasonable and believe nonsense, they are opening the door for the person to believe any other nonsense that they might stumble upon. After all, they have been trained to avoid critical thinking, and so they are ready to believe other bullshit as well. That preparation for believing bullshit is very dangerous and should be opposed.

If you replace "religion" by "other religions" (and pretend you were a Christian or something) your argument sounds exactly like what fundamentalist preachers say. Seriously, people need to start thinking before writing, you're basically advocating the inferiority of a group of people based on the fact that they have one tiny difference between them and you. Your slippery slope is ridiculous and fallacious, believing one bullshit claim doesn't mean you believe all bullshit claims, proof of that is theists who believe just one religion but not others.

C'mon, where's the complex argument and studies, etc? Why should I believe your opinion (because that's what it is)? I've met far too many great theists in my life - I know personal experience doesn't count as evidence, but I'm not proving anything, I'm just saying this sounds too much like a conspiracy theory for me to buy into it. The division between atheists and theists is insignificant compared to things like class and nationality. People are religious for all kinds of reason, and anyone who isn't retarded knows perfectly that religion appeals to people for many many reasons, otherwise no one would become religious in the first place - It's not a valid argument to say religion is poisonous and always opposes critical thinking because that's a hasty generalization and only serves the purpose of ridiculing - It doesn't work philosophically or scientifically - To back up your stance you would need to see every religion on earth and prove that every instance of religious thinking is anti-critical thinking.

People do not murder or discriminate because of not being religious. That does not mean that they cannot do bad things for other reasons.

No, but they can murder because they hate religion. That isn't worse or better than what religious nuts do. The doctrine people claim to follow isn't nearly as important as the damage they cause - I care about people's religion as much as I care about the murderer using a knife or a gun - It has some relevance, but nowhere near as much as the damage and suffering caused to the victims .
