Well...Dave ..
Funny thing is..
Multiculturalism works very well for us..
The melting pot of the US doesn't seem to be doing very well...
I pin it down to the fact the US insists everyone adopts the same behaviour as everyone else...and everyone wishes to be an individual ...which is at loggerhead with the national philosophy...
Thing is...we appreciate everyone's unique differences and wish everyone to ..be themselves...
Consequently..many immigrants ...and I have many friends who are...or rather ..were...who badly wanted to be "Canadian" ...and wanted to know the way to be like me...what does one say to that ?
Be yourself is all I can say.....
Kinda weird..

But our country is an odd one...
We don't have the problems other countries do..haven't ..in the past...the future.. .yet ...maybe...

But ....still the problem I fathom is...
People behave the same inevitably the world over...
Violence...
And that is one thing to protect from...regardless the side of the wall one and ones family is on..
If it stops people readily killing each other and such.....then big walls everywhere please..
