Who's the racist?

After very recently saying that we are no longer racists, the horrendous story of the disgustingly offensive abuse dished out by an Australian man on a bus last week seems to prove otherwise. He apparently objected to a young French woman singing a little song in her native (French) language. The rant and insulting outrage shown by this bogan was filmed by another passenger and showed such an ugly scene that I, and millions (I hope!) of others cringed in disbelief. The clip of that short 'video' has apparently 'gone viral' and spread across the world. My son, who lives in England, has seen it and wonders if he should venture 'back home' at all, if that is what to expect of Australians.
I tried to explain that this was a rare and randon occurrence, but information I have gathered (from speaking to others) tells me that, sadly, this is not so. That it is true that many Australians ARE racist - although not as blatanly offensive as the bus passenger.
One newspaper report (and there were many) had the comment that the abusive man would now be feeling very embarrassed and sorry for his actions.  I beg to differ. I think that the abusive, screaming man would, by now, probably be basking in the 'glory' of being a 'star' of TV and the Internet and be looking to his mates for praise. What a horrible thought...though probaby true! What have we become?
And, when you examine the feelings and hear the opinions of oh-so-many 'ordinary' Australians on the subject of refugees, you can see that the term "racist" appplies to all the people who harbour some sort of misguided resentment to the people who are fleeing oppression and attempting to find safety in a free & democratic nation.  I hang my head in shame!
