...This is yet another example of 'political correctness' going too far, I'm afraid I wouldn't even waste my time in thinking about a question like this, some people are just FAR TOO sensitive these days. I mean 'FLAGO' for christs sake, what a stupid suggestion! ...tell you what, lets not bother singing, telling jokes, being religious or doing anything in case we might remotely offend anyones modernised highly weakened sensibilities.
I'm not saying go out of your way to offend (for instance singing 'When Johnny come down to Hilo', in a West Indian Club...
"Well I neber seen de like since I bin born when a big buck nigger wid de seaboots on sez Johnny come down to Hilo...etc")
but just use common sense PLEASE!!!
