Yes , I know that this has been a topic of irritation.
However, there is one item that one needs to understand about it. This is the business of havng someone behind you 'grab' the top of your seat.
In the cramped concditions in Economy, it is usually the case that the person behind you simply CANNOT get out without 'grabbing' your seat if you are reclined. This is not rudeness or lack of consideration. It's really phsically impossible. I'm not referring to the person's physical fitness, or other personal things. I'm referring to stuff like Newton.
If you cannot get your center of gravity in front of your seat, you can't stand up to get out of it. In order to do that, you have to pull something in front of you until you can, and get your feet under that. The geometry of the reclined seats prevents you from 'getting up' without pulling yourself forward, and the only thing you have to do that with is the seat in front of you.
I know that this is an annoyance, However, as long as the distances between rows of seats remain as they are, people who recline need to be aware that they will probably be bothered by prople behind them pulling themselves up in order yo get out.
