People get confused, but the real problem is when they become mired in confusion. Happens all the time.
A lot of self described internet atheists or agnostics or whatever have seized upon this idea that “faith” is ignorance. Which of course has an element of truth in that faith deals with the unknown, and if you don’t know something you’re ignorant of it.
But faith applies to many things outside of a religious context, especially with respect to any future goal you are trying to achieve that you might not. You play in a sports contest believing you will win, but you also might lose. You invest in a business thinking it will succeed and maybe it does, but it can also fail and you don’t know which it will be going in. You bring a lawsuit thinking you will win, but of course you don’t know. Doing any of these things requires faith. In fact it would be irrational to do much of anything if you didn’t have “faith” in an outcome that is by definition uncertain going in.
The atheist’s quarrel is not with faith itself, because you practically cannot live as a human being without some faith in something, some belief in spite of uncertainty that makes it possible, indeed even rational to act. The atheist’s quarrel, rather, is with whatever religious people have faith in.
But in their zeal to paint religious belief as per se irrational they lapse into irrationality themselves. Questions of cosmology or what happens, if anything, after we die are, generally speaking, questions without knowable answers. Perhaps this makes them improper questions. Some schools of thought teach this, but then they wind up being more irrational than the questions themselves.
And the questions are not really irrational. They are probably better characterized as non-rational, or perhaps meta-rational.
Either way, they’re a step up from emotionally driven anti-religious hostility that leads people to sweeping and demonstrably wrong generalizations.
