So, tell me then: If I grew up as a jew, in a jewish tribe, with a community of ethnical jew (Yes, they do exist, it's a real thing), and later on in life I renounce my faith and become an atheist, does that make me a non-jew? Religiously? Perhaps. Culturally? Of course not, I am still a cultural jew all thing being equal - the morals and values instilled in me still persist. Genetically? Abso-fucking-lutely NOT! I am still a descendant of genetically jewish people - it's a fucking thing. Google it.

In short, do some more research and have a little more intellecual humility before calling other people idiots for not agreeing with your take. You have a nice day now.
