Since any religion and, in fact, all religions are merely hypotheses, you are welcome to believe in one absolutely but you are not free to bind others to the rules or beliefs of a religion.
Since any secular belief is merely a hypotheses you are welcome to believe in one but you are not free to bind others to the rules or beliefs of secularism. See, that mantra works both ways.
I am merely paraphrasing the Word of the God of Abraham, Issac, and Jacob.
It's not religion, it is faith, the belief in that which is unseen.
Religion is futile.
Not free to bind others?! You write in the very same sentence as one who still is suffering from some sort of spiritual or religious hangover yourself. Your strictures and your metaphysical constructs about freedom itself constitute a gigantic leap of irrational faith that cannot be justified or accounted for on your own terms. If on your assumptions cause and effect, chance and/or necessity of brute physical forces are all there is then there is no rational basis for any notion of "freedom" in the first place, much less any foundation for the ethical or noetic prescriptions you just propounded above. When matter in motion is all you've got then your notions of freedom and your proscriptions about what ought or ought not be bound are self-vitiating and absurd,
