Why is there a chat box?

[Guernica4000]

I usually play with the chat off as I multi-table and don't feel like typing "ty" every time I win a hand, but whenever I turn it on all I see is: "How do you call with that", "Moran" "FU" "nice catch fish", etc.

Basically it is a bunch of retards hiding behind their monitors being brave and insulting who ever beats them.

I even got insulted one time when my 25o BB was called by 4 players and with a flop of 225 I won a big pot and cracked Aces. The guy that slow played AA type “nice hand fish” :-) as always I abstained from saying anything but back to my question:

Why do we need a chat box?
