Actually, you can claim that your beliefs exempt you from taxes and get away with it, but the privilege is negotiated in the real world with real influences.
My friend, I mean no disrespect but you remind me of a younger me. I was a teenage agnostic, but the politics were too convenient...
I’m sure you want folks to take a medical treatment you believe will help them and others but we live in a diverse society that makes affordances for religious belief as a core pillar of our society.
Whether or not you want that to be so is not germane to the issue of how one, here and now, is presented with an exemption from an otherwise mandatory government edict.
I think you've stated the problem quite well: it's not a question of freedom, it's a religious and political issue.
BTW, you shouldn't risk getting COVID. if I remind you of your younger self, you must be in the vulnerable age bracket because I'm 50.
