The point is that the current Trump administration has a massive problem with immigration - that may or may not have consequences if you want to emigrate to the US. Or Brexit - if Johnson really delivers a no deal Brexit then UK economy is getting fucked over hard plus the right of free movement for EU citizens vanishes so you can get deported overnight.

Politics at this scale are life changing matters, and unfortunately with both the US and the UK governments it is clear that they are not run by competent people with a plan but by people who literally don't have any fixed opinion except nationalism - and that means that, as an immigrant, you're rock bottom of the ladder.

You are certainly entitled to your opinion, but other people may make a difference in what "is clear" to them.
