You dont have to feel ashamed of anything. There are rotten people in every nationality. In this airline harrasment case, it might be plain ignorance or indifference, thus both the crew & the "mis-behaving" passegers have contributed to the confusion.
Indians are travelling a lot more now than any of the previous generations, & there is a learning curve when it come to foreign cultures etc. So dont go over board saying that these guys made you feel ashamed to be an Indian.. did Iraq invasion by the American president make all the self-respecting Americans feel the same way?
Think about it & be judicious in shooting words, just for the effect!
