The main issue about these categories is that they've never been "big parts" of the characters of the MCU.

Captain America's reference is more a reference to his "outdated" personality than to his religious faith. Ivan Vanko's quote about making God bleed doesn't prove he is religious, as talking about God doesn't automatically mades you a religious person.

The same for the category about "atheist" characters. When was May confirmed to be an atheist? Given her background, she could be made a Buddhist or Taoist

What I see here with those categories is a source of speculation, which should not be on a wiki, and many many potential spam edits for adding categories without a proper source.
