Why are they evil?

As an European, they've never done anything to me. In fact, it's our countries that pillaged and conquered and colonized China. I've seen our troops on their borders many times, not even once the opposite.

And it's our own allies consistently creating trouble next to our borders in the middle east or north africa and causing millions of refugees that of course don't cross the atlantic.

Why is China evil exactly? And why are they only evil since they started mathing/outpacing US financial dominance?

It's the US spying our leaders (remember Merkel's phone), it's the US bugging our infrastructure, it's the US consistently creating business and legal issues, it's the US threatening our territories (Greenland), it's US cloud vendors violating our data sovereignity and sharing it with any US court or agency.

Why is China the boogeyman exactly?

You don't know about Tiananmen Square massacre? People thought China was evil even when they were dirt poor after their failed communist experiment.

You probably meant "threat" here instead of evil, and then it is obvious why nobody saw them as a threat when they were poor and weak, but now that they are big and strong people see them as a threat since they haven't exactly left their evil ways behind.
