Could atheist westerners, please explain?

Right.

Atlas has a problem with secularists who support things he is opposed to.

The implication is either that he has no problem with non-secularists who support things he is opposed to; or he assumes anyone against such things must be a secularist.

The first option is insane; the second shows a complete failure to understand what secular means. Take your pick, I'm going with the second. It's sad what propaganda can do to a person. When you can't use a word without adding a paragraph of unfounded agenda to it, you're off the rails.
