9. Flame Wars
You ever scroll down on a Youtube video to the comments section and see the middle part of a heated flame war happening. Arguing back and forth trying to justify themselves on points from their own perspective. Heres the thing about flame wars: nobody wins. You are never going to convince someone to admit they are wrong in front of the rest of the internet community. We have too much pride for that. Flame wars are usually dying down when someone begins pointing out the bad grammar, like thats so important on the internet. How is this destructive? Just watching this makes you lose intelligence and willing to jump in to defend the point you believe in. Its a real time waster when everything is said and done. Youtube religious or atheist videos, they are the worst offenders.
