For that last statement, you keep referring to people around you that would NOT even be the case for someone in front/behind you. Using an example of people in the seats beside you does NOT mean the person behind you will effect you.
I did not say anyone was more "deserving" of consideration. I said, one should not have to sit in discomfort for someone else's comfort. That is inconsideration from the one putting them in discomfort. I am really unsure how that is hard to understand. And again, the person behind is just sitting there. They aren't being inconsiderate. But now, according to you, they shouldn't even be asked if it will bother them.
As for "asking", I meant more of "alerting". Like "hey, i need to recline this seat a little, its putting a cramp in my neck. Just wanted to make sure it wasn't going to hurt anything". That is consideration. If the reclined seat isn't going to make any more difference than everyone is saying, then there shouldn't be a problem if done in that way.
But, hey, if you choose to be "considerate" of others by twisting up like a pretzel to make sure those on either side of you have all the room they need, more power to you. Just understand that you are allowing them to continue to be inconsiderate of you.
So, I wanted to see with my own eyes what reclining will do to the passenger behind you. So I googled. There are literally thousands of articles on this subject! Wow! Did not know there was this whole controversy out there! Lots of etiquette lists that say when to recline and when not to. Most are about what is being said here. None saying "well its only 3 inches it doesn't hurt anything", but agreeing with some of the complaints against reclining and why one should be mindful of the person behind them in those cases. They aren't saying don't, just be careful when. Seems like a good compromise to the whole thing.
