Back to post #1: the woman who wouldn't help the family with the special needs child? Honestly, someone should've helped the b#stard descend the steps a bit quicker. That's just appalling.
You're missing the point FHA, special needs pax are preloaded and looked after on other airlines.
And the woman may have paid for the privilege of selecting that seat - perhaps she is claustrophobic or has some other reason she needed to sit there.
Without knowing the facts, you are judging prematurely, for example I could conclude from your expressed view that you are an intellectual lightweight, incapable of expressing yourself with resort to bad language, who doesn't think things through and exhorts violence as a solution.
I doubt that that is fair comment and neither is your post.
