It is amusing to note the simplicity of people when everything is put into context. In general, the majority are cowards; simply hiding behind digital masking or the more archaic cambium.
It would be redundant to call them anything more than cowardly, as everything negative can be boiled down to that one simple word.
The most cowardly are often the most naive. They believe that they can change those around them with ease. It is always a hilarious exhibition. Watching them flounder and pounce to one subject or another until they finally reach the ad hominem portion of their argument, if indeed it was not the first.
At this point you can easily entertain yourself with a quick wit and the will not to use their own tactics. Alas, this can only last so long because these poor, ignorant, fools can only produce a very limited amount of slurs and attacks based on your character. They become repetitive and stagnate in their own delusions.
After that, it's always best to just simply quit the argument and let them believe they have won. In this way, you provide somebody else with a short burst of entertainment.
