Airplane Seats

Am I one of the precious few people who view putting your airplane seat back as rude? When I'm on a plane I have basically enough room to have my knees rest an inch away from the seat in front of me. Then when the plane gets up to where it needs to be and the airplane folk make the announcement that everyone's free to adjust their seats, the person in front of me--usually some fellow with glasses and a roll of hot dogs on the back of the neck--throws the seat back as far as it can go, crushing my legs. The only reason my legs are being crushed is to slightly benefit the man sitting in front of me. Airplane seats aren't comfortable, pushing the seat back a couple inches and making me more miserable isn't going to make your flight a maginificent dream of comfort. Thank you.
