Copied from vocabulary.com
“To be dogmatic is to follow a set of rules no matter what. The rules might be religious, philosophical, or made-up, but dogmatic people would never waver in their beliefs so don't even think of trying to change their minds”.
I find the atheist movement becoming more and more zealous as well as intolerant and disrespectful to people of faith.
