Precisely my point. People say stupid shit like this BECAUSE they expect to be protected by anonymity. Think the drag queen MeSarah would be bashing on Tom's wife if he was standing next to him? Uh no. Just another coward.
To be honest, I think people have become a lot more rude in real life as a sort of flow on effect of not applying a filter to what they say online. People have become used to venting every little frustration online and it seems to diminish the capacity of many to deal with frustration or disappointment in real life in a non-confrontational manner.
