Weeaboo is a word created to insult non Japanese fans who prefer Japanese over English. It's an attempt to belittle their opinion on the matter by accentuating a trivial detail and blowing it out of proportion, it is the definition of hyperbole. You could have said the exact same sentence minus the term weeaboo and gotten the same point across, adding weeaboo you preemptiveley tried to belittle their feeling on the subject.
Three things to keep in mind:
1. I don't care what audio you prefer.
2. See the title? English Dub, right? It's very annoying to see people enter a thread with the title "English Dub" in it and then give you their preferences.(Sub > Dub) When in fact, I'm not even asking you preferences. This is actually a informative thread. So w-why even post something like that? Therefore, you probably would fall under this term, "weeaboo". If you're a Sub fan by any chance, you probably wouldn't enter this thread. Because it really has nothing to do with you. Maybe out of curiosity, but then again you have no reason to be offended. Why? You're not apart of the percentage that post "Sub > Dub" in a thread that is about the English Dub.
Now, let's get to the good part.
3. Weeaboo doesn't mean exactly what you said. A weeaboo is person that acts very interested in Japanese stuff, but have the slightest clue about Japanese. For example: Naruto english voice actor is played by a woman, but oblivious to fact that Naruto's Japanese voice actor is also a woman.
See... when Dub is mention topics like this start.
