I was already not going to the US anyway. At least not by plane. I've seen and heard enough about TSA to know it's not a place where I want to go. Ever since 9/11, their paranoia and security theatres are too much for me. I even avoid flights that have connections in the US.
I considered going to Vermont on my bike to try rail trails and loop back in Canada, but even then, the prospect of going through US customs is enough to prevent me doing it.
Plus, I'm part of minorities, defend them, and know that I would have to be careful about what I say in some states. And I also don't feel safe around people carrying guns everywhere.
Trump just pushed everything to the extreme. Crossing the border was already a possible shitty experience, now the chances of being treated like a criminal without any rights are even higher. No point in trying.
