Ahemmm... well I don't like to admit this, but the truth of the matter is... I am probably one of those people...
So, I'll give my perspective.
We just like to debate. Sometimes it is oneupmanship. Other times it is just because we are so excited about whatever we are involved in.
On the other hand, our skins are usually thick enough that you can spell it out straight to us. "I'm sure you don't mean to try to one up me, but sometimes it comes across that way." (when it is happening).
Good luck. Chin up. Mostly I would say just ignore us.
