I think once I know you are religious I immediately question your intelligence on every single topic
That's quite harsh.  Why do you question the intelligence of religious people?
Because most religions have a very weak base, most religious people are afraid of questions and they have a fragile mind
In a free country people are free to practice any religion and  beliefs.  It's wrong to judge their intelligence based on their religiosity.
And which religion out there is practiced by a person with a logical mind?
Don't you think that is an over generalization?  There are many reasons as to why a person practices their faith, and many logical and intelligent people also are religious.  It's not right to associate intelligence and faith, perhaps you should try and figure out why some people feel the way they do?
