[Someday]

A bird doesn't have to be able to fly.

So...people are birds because they can't fly??

Apples to oranges.

I'd suggest that Freethinking is allowing yourself to consider all possibilities, however improbable. You are then able to reject the possibilities that do not fit with your current view of the world.

I'd agree, that's what one ought to be.
That's not the brand that is being put forth on the internet. Nor is that the sort of thing being suggested by the apostles of militant atheism. They preach Freedom from any religious thought first. Thus they confine their thought, not free it.
