Earlier quoted context omitted.
The post you replied to (with the "GooGoo Fanboy" term) was overly vociferous. But that's when it's most important to avoid words like 'fanboy' because otherwise discussion dies. People probably thought you had a good point, but you lose that when you use words like 'googoo fanboy'. And that'll do nothing to sway the person you're replying to. If anything it'll just entrench them even more.
I didn't really think so. I thought GooGoo Fanboy was apt satire myself. The hyperbole of the original poster clearly showed that he/she was already very entrenched anyway. And considering it's possible that debating someone's strongly held points with logical counter points will only irrationally strengthen the person's original beliefs anyway, I think humor was appropriate: http://youarenotsosmart.com/2011/06/10/th…
So I think it's still "worth it" to respond in a meaningful way, even though you may not convince the original poster.
