Thank you! You pay for the seat, the space under the seat ahead of you, and the ability to recline. All of that space is rightfully yours. Everyone else on the flight pays for the same and is rightfully theirs. People who don't understand that need to re-evaluate why they are flying. Blocking someone from reclining, in my book at least is a sociopathic move.

There is worse behavior on planes of course. I was once on a flight where I put my backpack under the seat ahead of me and the woman sitting in that seat started kicking it. I firmly pointed out to her that there was a laptop and camera in the bag and that she needed to stop. She informed me that the space under her seat was hers and that I needed to move my bag. The dispute finally ended when she hit the call button and the attending flight attendant eventually had to have her removed from the plane.
