For example, all the Christians whining about Christianity not being tolerated. They're getting it wrong - nobody is saying don't be Christian. They break the contract by imposing their specific values on everyone else by force.

Dude, that’s literally the paradox of tolerance.

They take advantage of the goodwill and social norms of the rest of the population in the interest of imposing their specific values on everyone else by force. They don’t believe that that sense of goodwill and social norms are things they have to abide by, but they recognize the power of exploiting a system against itself, and that power is very real. The initial stages of this generally involve aggressively exploiting the letter of the law, and often, working entirely contrary to the spirit of the law.
