All religions teach you to do some activities or to follow a set of principles. To obligate you to those principles, there is a supernatural energy or power (which is rate of energy 😆) known as God/Allah/Krishna/Vishnu/bla bla which will punish you or award you for your acts, depending on how fanatical your religion is. You try to follow those principles for the same reason in abstract, but you make different theories about it, depending on your level of education. And thats how you say Geeta/Kuran/Bla bla have different meaning for different person. But the fact is, it is nonsense to say that one statement have different meaning for different people.
If you are an atheist, you don't think you are obligated to the any of such principles, and hence you don't follow them. And hence you are irreligious.
Religions Kill. Abstract of every religions is: create a belief system based on traditions/so called religious books/unwritten stories. Treat your belief as facts. Now, instead of having a belief system backed with facts, you have so called facts based on beliefs. You fight for it, die for it, kill for it, because, you know, your belief can be broken, since it is illogical. Why no body has to fight to save science, or scientific methodologies and procedures? Why if someone say earth is flat, we don't kill them? Because we know our belief system is based on facts or at least a systematic way to investigate things. We first tried to discover facts and then nurtured our belief system upon it, unlike religious people. But, why someone who believe earth is flat will kill me or will be aggressive about it and tell me not to discuss it, if I would claim otherwise? Because they know, if I will be alive, I will question them till their belief will break down.
These religions have been biggest killer in the human history. WW2 is one example, in which about 60 Lakhs Jews were killed. Several countries are based on religions. They fight with each other, kill each other. Riots, thousands of riots have happened across the world. Terrorism have deep roots in religions.
Religions Kill.
