Your assertions are quite off target in the sense that Christianity (New Testament only kind) is a religion that is already more suited to secularism, just like the faiths of Buddhism or Sikhism.
It's not a question of secularism mocking, satirising or humbling the crap out of anything, but more so, that the nature of Christianity allows this to happen.
As your argument seems to stem from the premise made above ("Christianity is more amenable to secularist principles"
, this follow-on argument is again incorrect.
You also seem to have conflated the secularism with a propagation of inalienable rights, unseemly understanding what either concepts entail.
