1. Recline
If everyone reclined, everyone would be comfortable 
2. Keep your PEDs on
Same as what happens now, considering the large number of people that keep these on, whether concealed or not.
3. Take your screaming babies on when it's discretionary travel
Who are you to expect others to not travel with their kids? And that's putting aside the fact that you have no idea why they're traveling with an infant.
4. Bull your way to the front when deplaning or put your rollaboard over row 6 when you're sitting in row 26
5. Reserve window/aisle then talk loudly to each other.
6. Bring your non-legitimate service animal onboard who invades someone else's space
7. Demand to be moved to keep your family (grown man, grown woman, 10 and 12 year old) together.
8. Can't deal with the compromises of having the window seat or not having the window seat (same with aisle)
No problem with these..
9. Drink a lot of fluid knowing that the flight could be bumpy and the SB sign might not go off or the aisle person (in fairness see #8) will have to get up 6 times so you could drink 10 beers
This is the epitome of self-righteousness. You act how YOU think it's right to act, and expect others to act the same way. Guess what, some people need alcohol on a flight to calm down, some need to drink a lot of water to stay hydrated.. If you're in the aisle, expect to get up.
10. Take you damn slow time exiting the aircraft (OK if you let people in your row out and wait until everyone is off).
Some people are physically slow, others slow-minded. Perhaps everyone should remain seated until Flubber2012 deplanes as he is the only one with a tight connection.
Do you realize that you get away with these things because people like me play by the rules and societal norms. Personally, I would like to give a forearm shimmy to the guy who holds up deplaning while I have a short connection. Howver, the law and common courtesy prevent me from doing so.
Sounds like it's only the law. Common courtesy prevents me from even considering to hurt people in line because just because they're slow.
Ever consider what would happen if everyone acted like you?
