I suppose you could consider that a form of insecurity not really. One of my favorite results from pysch research was that large, physically aggressive men are not in fact covering up insecurity. In general, they tend to have very good self esteem. Which frankly makes sense. Why? Because few people want to step to a large, physically aggressive guy and tell them they have some stupid ideas. Real life example: any NFL pre-game show. These guys are sling blade level stupid yet they have incredibly high opinions of themselves.
