You can't be serious!
Tall people are nothing except uncomforatble themselves. They don't bother the airline or any other passenger.
Actually, I'm for separate seating on airplanes. There's no reason why women should get the same amount of room as men. I have to fly first class to have the same relative amount of room as my wife. If we're really going to have equality in this country, then everyone should have the same amount of distance from his/her knees to the seat in front of him/her, or be compensated for life by the airline.
