The point in question was about "routines in your country that I would consider barbaric and and inhumane and and would be appalled at being subjected to". You aren't a strolling cat and you aren't a baby in a pushchair, so those particular examples are not really relevant in this context.

I repeat, if you as a visitor was treated by the authorities in a way that you felt was barbaric and inhumane that would be wrong. If it turned out that ordinary people in the country were being treated in the same way, perhaps because of some unconsidered bureaucratic procedure, that would just make it worse. And as I said, you'd deserve to be thanked for bringing the situation to public attention, because that way it might get changed.

And I hope that that is in fact the way most Americans would react to this affair. As the saying goes, "My country, right or wrong; if right, to be kept right; and if wrong, to be set right."
