> As a non-Christian observer, Christianity does seem to be the only religion that it is acceptable to mock, deride, and make a scapegoat of.

Christianity is the largest religious group in the world, which dominates free and open societies that enjoy freedom of speech without fear of repercussion. The places where Christianity gets mocked and ridiculed are the same places where heads of state and leading politicians are freely mocked and ridiculed.

That does not mean Christians are oppressed. It just means that their societies are tolerant, like... Well, like exactly what the religion defends.

Just because we, in western countries, feel free to make jokes about religious groups that doesn't mean they are being oppressed.
