This comment is bizarre. Literally nothing about this policy change destroys the US or any principle outlined in the Constitution.

It removes a convenience that was sometimes abused (see the top post) and makes it harder to bypass US law to get a visa.

I imagine it's more of a comment about the underlying trend.

I can't say I have any loyalty to the government or the constitution, but i will say that our willingness to accept immigrants is far and away the best thing about this place.
