I don't agree with your observation - but even if it was true is there any surprise that posters concentrate on: the actions of our own government; our best international friend and ally (let's see how the Brexit trade deal turns out!); and the government of a racist state built on the embers of a UK mandate, protected by the UK and US for all its war crimes and nuclear weapons programmes, and represented in the heart of our main political parties in Westminster.
If I ever get wound up about potholes I am more likely to complain about the ones in my street than the worse ones in Mumbai.
That may seem anti-western to you and evidence of bias - but it is a very rational response to most of us!
