Got anything to back your bullshit up with, or is that just a fervent desire on your part?
“Bullshit†is all that comment deserves, as should be self-evident.
There is no wall along the US-Canada border, and no plans to build one. Does that mean that neither country is well-defined? Do both countries lack sovereignty because there is no wall along that border?
Is it impossible to distinguish between Canada as a nation and the US as a nation because there is no wall between them?
Merely stating the conclusions that stupid comment necessarily entails should be more than sufficient to demonstrate what pure unadulterated bullshit that statement is.
