I greatly agree with you on this. Religion is man made. Some humans believe they have to have something to believe in or they fall apart in the balance of life. I dont believe if there is a god or whatever, that he made about 100 different religions and there all right.
Either way we all have our own religion even though it has no name, we believe in what we want.
Parents arent right sometimes with enforcing children to believe in something when they really dont. To as what religion is right we will never know, but kan only guess or estimate. I by my parents was Roman Catholic once, then Satanist and back and forth with atheist.
I have nothing against anyones beliefs, they belong to the person who believes it and not my own. Thats my opinion.
