People will always protest against things that are more immediately visible to them than things they read about in infrequent news articles. That's just human nature.
You don't have to protest every cause to protest any cause. You can even protest things that, taken together, demonstrate you hold ideologically inconsistent views, if you want. That's on you.
That doesn't help your argument. They were aware Obama killed a quarter of a million people and did nothing. Meanwhile Trump inconveniences some travelers and somehow he's the monster worth protesting. Get real.
I'll thank you to reconsider your projections of people you've never met.
This in a nutshell is why things will get worse stateside. There will be those who write off the circumstances behind where we find ourselves today as human nature (an absolution of sorts, a moral line item to be paid when the circumstances are brought to their attention, not too dissimilar from the likes of HSBC et al when they pay penance in the form of monetary notes for aiding and abetting criminals as defined by a given state) and join the protest, and there will be those who apply the tools refined during war agaisnt their "own" at such protests.
Either way, only those who come out ahead outside of any virtue signaling will probably be the suppliers of such tools.
