anti-recline device causes fight on plane/2 kicked off

Did I pay for a seat and the space my legs take up on the plane? If my knees are right up against the back of their chair is this my space or theirs? A reclining seat now is taking away from the space I paid for. Like I originally said, just make all seats unable to recline like they did with the one's in front of the emergency rows and no more problems.

the fact is that the seat reclines. that reclined position is space i paid for. don't like it pay up and move to first class. so simple.
