That's not what you said. You gave a few examples of how you've made relatives fly to you rather than vice-versa and declared that "As far as I'm concerned, kids under 3 should not be allowed to fly". In other words, children never have a valid reason for flying, whereas you always do.

Of course, what you are really saying is that population X should be denied right Y because their presence diminishes your enjoyment of right Y. That's the entitlement BS. Perhaps you'd be open to a compromise? How about you allow families and other undesirables to board, but make them sit at the back of the airbus. They'll still be able to travel, but at least the segregation keeps them from bothering the more deserving folks up front.
