I agree. On an individual level, it would be a losing battle to convince everyone that their superstitions, which includes much more than religious beliefs, are not true.
However, government should always be clearly separated from religious institutions and ideology. Additionally, religious institutions must always be held to the standard of the law and not allowed special exceptions. Also, every individual should have unrestricted public access to information pertaining to other religions and non religious ideology.
Finally, don’t be afraid to call people out on logical contradictions pertaining to any superstitious belief, especially religious beliefs.
