I don't think it can be the point, as the point was "bad things happen in other places and yet people don't care about it, they criticize US because it's the current trend".

One of my reaction was that one of their examples (immigration in UK/EU) seems to be an exact counter-examples where US people are overestimating crises that are outside of US and point the fingers.

As for the situation in UK/EU, a real reaction that happened in UK/EU is that if something like ICE was to happen in UK/EU, the population will never accept that (they may be wrong, but they are right that there is something there). Not because immigration laws are less unfair or less cruel in UK/EU, but because in US, there was not even the decency of pretending a due-process was needed. You can deport in UK/EU, but it is done by people who follow the rules and who are not particularly "against" people they deport. With ICE, it looks like cowboys who openly don't care about due-process. In UK/EU, the machine can be cruel. In US, there is no machine at all, just people openly showing they don't care.
