Not all relgion is entirely faith based or illogical. The type of religion you are talking about is called fideistic religion.

Some of it is merely implausible as opposed to illogical. Examples: Trinity 3=1 is inherently illogical. Resurrection, not inherently illogical, but highly implausible. We would have to assume that one event occurred that was totally out of synch about everything we know about human life. Most people claim to believe in Jesus’s resurrection based on faith but if you come across one who appeals to “historical evidence” i.e. the Bible there is at least a possibility of persuading them they are wrong (however, the likelihood that you will change their mind is almost as unlikely as Resurrection itself).

Some religious believers are however comfortable with their religious beliefs because they have never noticed that they are either implausbile or illogical. (Not ever religious believer takes Tertullian’s view, I believe because it is absurd. If they did, then you are right it would be futile to try and reason with them.)

By asking a question that points out something illogical, assuming that they don’t already know it’s illogical and not care (Tertullian’s position), you’re hoping to change their mind or if not change their mind or at least shake their dogmatic certainty a little bit.

You have an incorrect definition of faith as used in scripture.

Because as you stated faith is illogical and irrational such is the way of love , some people so strongly for somone or something no matter if there was love was proved wrong they would fight for it such is the way of faith that with its irrationality is that there is no way to prove there faith is true or not as we cant prove there is a god and there isnt and so faith continues on blind hope and thereofre it is a viscious circle that will continue as long as people have emotions.

People need to think. Badly. What do you think brought this state into the world?

As the first one above said, it was fiath that flew planes into the twin towers… and faith that is currently launching rockets in the middle east.

People must be taught to think rationally, lest it destroy our world.

Faith and Logic are not necessarily opposites. You have faith that the Chair you are sitting in will hold you up—that is also logical.

EXACTLY

And then they don’t get why their analogies are bad.

Faith flew planes into buildings. If you have no logic and no evidence, you have nothing.
