It's called freedom of choice, and if I choose not to fly with an airline because I don't like the colour of it's seats or for any other whimsical reason, it is my choice, and I don't need to justify it to anyone.
Agreed and in the same vein me flying Ryanair for my own, no doubt, 'whimsical' reasons, doesn't make me an 'idiot'.
The poster above who compared this all to a religious spat hit the nail on the head. Anyone would think that O'Leary was slaughtering the first-born of anyone who refuses to buy his tickets.
Pay your money and take your choice folks. It really is that simple.
