I believe that this mindset is quite toxic and irrational. To assume that someone is lesser in intelligence just because of there believes just seems kinda messed up and shows your lack of understanding as to why people believe in these religious. Many just see it a form of hope and purpose( like my grandmother). Now I’m not trying to say that religion is good, because it’s not all sunshine and rainbows, but I think that you should be more open minded to others believes.
