"You would have been stopped at the border for that at any point in the last 100 years."

Comparing an action that occurs in our world today to a same action occurring 100 years ago does not invalidate the parallel being drawn because you are not accounting for the world being completely different.

As I see it, the technology advancements over that 100 year period have created a world that's much more sensitive to any encroachment in freedoms. So that same action can and, I believe, does align well to establish the parallel being drawn.
