I liked what the old lady said "People pay for their seats and they want to push it backward or forward, that's their God given right." First, God given right?! I hate when ignorant people use catchphrases. Second, And yet I paid for my seat also and I don't want to have to contort myself so you can fool yourself into believing that you're somehow more comfortable.
I'm 6'4" and have never leaned my seat back except to see what it was like. There is no difference, except that you pi$$ off the person behind you. It's amazing that people get so worked up over the ability to "recline" their seats a measly 2 or 3 inches. It doesn't bother me when people in front of me recline unless I'm caught off guard and they crush my knee with the metal seat frame. Well, it does bother me. Sometimes it really hurts.
If I'm in an isle seat, my legs are forced into the isle and people have to dodge around them. I don't cram them in unless the FA asks me to, then I mention how I have to put them there because the seat in front is reclined. And if you're in a window seat, your a$$ is that much closer to the poor sap you have to climb over to get to the bathroom. I think that they should just disable the recline altogether.
