So, I was perusing one of the recent threads (Legal immigration)on Immigration, and these questions occurred to me:
Can a case be made for construction of walls/fences/barriers on some or all of the land borders (and perhaps some sea borders? Dunno how that would work...) of the US?
If you support such, why?
If you oppose such, Why?
And, whether you support or oppose such, are there variables involved that might convince you to switch?
And other questions in that vein.
