Even if you cannot prove it doesn't mean it is necessarily perception. Just because one cannot prove something, doesn't mean it's not real. Can you prove the numbers haven't risen? The main issue is the arbitrary detention. Getting turned away at the border and taking the next flight home is one thing, but getting locked up seems scary.
You claim it’s a perception issue. We say it doesn’t matter if it’s perception. Even one wrongful detention is too much. And people should avoid going to the US in this climate. My past tweets would probably be enough to get me detained.
Am I sure about that? No.
Can anyone be sure nowadays?
Is that just perception? Maybe. Will I avoid going to the US anyway? Yes.
If you’re still looking for a trend, here’s one: We don’t trust the US anymore. And there’s nothing their government does or says to reassure us.
