I understand where you are coming from on your definitions of those two words, but most people of faith I know use them interchangeably. :) I remember once talking to a friend who had grown up in a very fundamentalist family and even went to a college that taught creationist conforming geology. It wasn't until he switched schools that he was even exposed to different ideas. Many many people who may even have "convictions" can learn to accept new ideas. Just don't get so fed up that you forget to address them too.
