Just because China is bad, doesn't mean the US isn't.
Just look at how willingly the US public voted in Trump who is demonstrably a horrible, spiteful, selfish person, a compulsive liar who constantly contradicts himself, and he's not even a good businessman, he's an even worse christian for all those who care about that.
And yet there's a neverending propaganda machine convincing people that he's the kind of person that should be running a country.
Both sides are the same!
This is true, but I more often see the opposite implied: Because the US is bad, Russia, China, and Iran shouldn’t be criticised.
It’s often goes:
A: “China did a bad thing.”
B: “Yeah well, America did a bad thing too, you propaganda-addled fool.”
A: “Yes, but all these people in China...”
B: “Hypocrite! Dupe! Racist!”
