All reddit users are just Paul Markham using different names.
 

1. Smart enough to read / study a certain topic, not smart enough to understand what they've read.
2. Has an opinion about everything but especially things they have zero experience in.
3. Will argue about the topics they don't understand until the end of time.
4. Cannot be wrong. No amount of proof is ever sufficient, they will double / triple / quadruple down on the stupid or deflect completely by calling you a troll.
5. 55555555

Like to go through history and bring up irrelevant points nobody cares about as proof of some defect they claim against you.

6. Keep posting even when nobody is listening.
