Okay then. I have traveled across the border all my life and I have written proof for the last 15 years that amounts to over 10 pages of documented entry to and from the US so I know of what I speak.

I have met the occasional incompetent border guard going into the US and have had to watch them bury themselves in irrelevant questions, but I have never met either a rude or abusive one and I really doubt the day shift at the border cares about your political beliefs. Night shift, admittedly, tends to attract the weirds.
