Atheist, childfree and milenial, I think I am fit to answer all of this

-Religion, to me, is a big no. I have good friend who is christian and sometime I even join his church's charity events, but I will never join them even how close we become. The biggest reason to me to say no, is that they indoctrinate young mind and discourage them to think critically. I am totally fine with adult voluntary to join the church and even bring children with them, but the children need to be exclude from the teaching, aside from the message like god love you and we are always here to help.

Why? Because when you let religion do all the teaching and influent, things get crazy, a lot of them abuse power, cons followers, molest children... Sure a lot of them wont do that, but I refuse to let the life and freedom of ones fall into the hand of religion. In my opinion I support them to become some communities organization but if I have the power I would strip away all the political power of religion in the world. You are free to believe what you want, but you are not allowed to indoctrinate young people and teach them falsehood. I dont care how many people follow christian in that area, if only one atheist/muslim(or anything) person is there, they must have the right to follow whatever belief they held without being bullied, threaten or denied rights.

Oh and dont say that religions never do that, you guy have been waging wars with everyone who dont hold your point of view since ever. Different religion or atheist, doesnt matter to me. And thank to internet, people get acess to the world, belief get challenged, do you know what kind of people who have a lot of belief in religion? People in remote region with not many acess to information.

So, tldr: Believe what you want, I dont care, but dont force it to other people's throat.
