INTJ's will only overpower if they feel they are honestly 100% right. While INTJ's love to debate over reason, if they are healthy, they should be able to see your logic if presented in an appropriate manner, and then back your opinion. I know I do.
I think you are just stereotyping INTJ's who are vocal and possibly under developed.
