Wiki - The paradox of tolerance states that if a society is tolerant without limit, its ability to be tolerant is eventually ceased or destroyed by the intolerant. Karl Popper described it as the seemingly self-contradictory idea that in order to maintain a tolerant society, the society must retain the right to be intolerant of intolerance.
That’s a fair point. I think it’s more about respecting and tolerating people’s personal agency and bodily autonomy. You don’t need to respect someone’s beliefs in order to tolerate them. I personally think religion is idiotic, but I tolerate it existing. I recognise that it isn’t my right to dictate whether someone worships or not.
It all naturally needs to work within the framework of society. You can’t force someone not to litter, but if littering is a fineable offense, then the litterer must recognise that while no one can stop them from littering, there can be consequences to their actions.
