"We may conclude from the Pew surveys that the more you're convinced of God's existence, the higher the chance you're intolerant and narrow-minded."
Actually, that's not a good inference from the data. For instance, look at the data on this link:
http://religions.pewforum.org/portraits
If for instance, you look at the Catholic portrait, you'd see that 77% said "There is MORE than one true way to interpret the teachings of my religion" and 79% said "Many religions can lead to eternal life", although 72% are absolutely certain that God exists.
So being convinced of God's existence, by itself, does not make it highly likely that you're intolerant and narrow-minded.
One of the factors that are more likely to cause intolerance is rigid interpretation of religious teachings, not sincere belief, like the Witnesses' 77% saying "There is only ONE true way to interpret the teachings of my religion."
Also, the pew studies clearly state that "most Americans have a non-dogmatic approach to faith. A majority of those who are affiliated with a religion, for instance, do not believe their religion is the only way to salvation. And almost the same number believes that there is more than one true way to interpret the teachings of their religion."
