Thanks to the Australians and all other allies in the field.
I hope you don’t have an ACLU (Australian Civil Liberties Union).
Because if you do, they won’t be happy seeing folks in uniform...
singing Christmas carols!!!
For some reason, our Civil Liberties types seem to have got this one right - a rare event, it sometimes seems. They are fine with Christian observances as long as other faiths get the same opportunity when appropriate - a much more reasonable position than trying to block Christians from expressing their faith.
