In fear of being labeled a liberal - which would be a hard thing to take for a dyed in the wool conservative - I disagree with anyone having the right to not allow boarding to anyone based on race, religion or looks or bad vibes or funny feelings or whatever. If there is a demonstratable reason to suspect someone, pitch them from the plane headfirst without benefit of airstairs but don't deny boarding to someone whose only crime is to look middle eastern. Maybe as a pax and not flight crew I just see this from a different angle but if anyone is arbitrarily banned from a flight we all have given up a bit of our rights. On the subject of those who celebrate the cold blooded murder of 5000 innocent civilians including untold numbers of believers of Islam in the WTC on 9-11 - you should be on your knees begging for forgiveness from the civilized world - MURDER IS NOT A RELIGIOUS ACT!
