When I was an atheist I spent so much energy trying to convince myself and others that hell didn't exist (cringe I know). But seeing the way modern Hollywood operates in regards to mocking Christianity and seeing how the entire industry is dedicated to glorifying the most sinful aspects of humanity I'm more than convinced that fiery punishment is waiting for these "people".
There's no actual risk involved in attacking Christianity. You won't get deplatformed, you won't get assaulted and you won't get murdered, because Christians unfortunately are too civilized for that, and they're made to pay dearly for their niceness and decency.
Muslims are murderous, subhuman savages, and criticism of Islam and Muslims is actively suppressed for that reason (well, that and Islam being considered a "brown-person religion").
