useless fanboy

An especially nasty version of the usual fanboy that in addition to being fanatic about a subject is so arrogant about its superiority (or its opposition's inferiority, in many cases) that they'll never budge an inch even if you hit them with a two-ton truck of reasoning against it. As such, they are USELESS in conversations that might involve someone saying (or implying) something negative about the subject they're a fanboy of.

Useless fanboys can be seen everywhere where opinions clash, from brand loyalty to politics. They are the enemy of rational discussion and all those that practice it. Avoid these kinds of people at all costs.
