It's Christmas in Toronto, and all the angels sing...
One would be forgiven for thinking that maybe the cross was made illegal or something, but that's the way of the discussion of these things.
One would also be forgiven for believing that all I ever do is complain about things without offering up solutions. Because this one's so easy, I'll do just that very thing. The obvious solution to this problem is to decorate public places for all religious holidays, be they Sikh, Hindi, Buddhist, Christian, Muslim, Jewish, whatever. We have to draw the line somewhere of course, but you know what I mean - put the damn tree back up and stick a Menorah there, too. And then explore the calendar of events for major Canadian religions and celebrate those, too. Either that, or don't do any of them.
As for us atheists, we're an understanding lot. We can let you honour your gods in any way you see fit without feeling shame, remorse, or feelings of exclusion. Just so long as the religious acoutrements stay outside the courtroom.
