1. You may say whatever you like, so long as you sincerely believe it to be true, or it is witty or comical and relates to the topic or the person you're talking to. No holds barred.

2. You should not ignore someone or be dismissive of them just because you don't like something they say. We should act like men, not like cowards. Confronting truth in all forms is part and parcel of philosophy as a noble pursuit.

3. Always remain on point, excepting a permissible degree for sake of comedy.

4. You should not evade the burden of justification or refuse to be reasonable when appropriate, which is almost always - setting aside some amount of permissible facetiousness - or withhold beliefs from scrutiny. If you cannot reasonably justify a belief or aren't willing to do so when confronted or challenged, then you should be explicit and honest about it.

5. Try to foster as much as possible an awareness of your own psychological defence mechanisms and those of others. Point them out if necessary, even if this is considered taboo.

6. Speaking of taboo, and of popular etiquette, disregard it unless it is truly of depth.

7. Always aim to develop and apply critical thinking skills, especially the skill of identifying fallacies.

8. Always be concise. Avoid obscure jargon where possible.

9. Learn the difference between facetiousness and satire, and between real insults and things you just find rude or insulting.
