Taboo is one of those people that it's always much easier to just ignore.
Sometimes he'll maybe have something interesting to discuss or say, but other times he'll be quite stupid or unnecesarilly insulting.
And since he's too arrogant or too stupid to listen to anyone else when they comment on this, it's easy to just ignore him and let him think he's accomplished something.
While he's busy pleasuring himself to the image of his ego we can carry on like normal.
I wouldn't bother getting too worked up over him.
