That is true of everything that isn’t barred by the fundamentals of physics, and disingenuous and you know it.
You can murder people, you can enslave others, Hindus can slaughter and eat cows, etc, you just don’t want to because it’s illegal.
For most religious people the tenents of their faith are core to their being and not something they just kinda like. Otherwise they tend to deconstruct from their religion after the inertia runs out. That’s why religion in the West is on a downward trajectory outside of Islam which is driven by immigration.
I fully support reproductive rights as much as the next guy, but let’s not pretend that the person outlined above single issue voting against abortion isn’t looking at the other side as otherwise great but you have to accept a few sanctioned murders. You would probably be single issue voting if we had a modern Aztec government that was close to a utopia but practiced human sacrifices to Quetzalcoatl because it maintains prosperity.
Can you really choose what you believe, though? Could you make yourself stop believing in gravity or anything else you truly believe in? Could you make yourself believe in flat earth if someone told you too? The mind isn’t something so malleable that you get to pick and choose your beliefs like a salad bar. Religious beliefs are one of the hardest to change, with even those leaving organized religion ending up frequently still believing in a God of some kind.
I grew up in a religious household but open minded and science oriented, so I deconverted and consider myself an atheist. I whole heartedly agree that the world would be a better place without religion, it’s the world’s greatest con job, but let’s not kid ourselves about the spectrum of the word choice here. It’s a (lesser) reverse of the religious telling anyone that isn’t heteronormative in any way that those are choices. It’s all brain chemistry occurring in a black box that we know vanishingly little about for how much we have studied it.
