No I don't have evidence, and I was going to include that I don't have evidence in my comment, but didn't. I was merely stating a possibility in answer to your question. Maybe you should reply to my second paragraph instead.

Edit: I don't know about the intricacies of political correctness, but somehow "trump supporter" feels ok, maybe because it has two words and "supporter" balances "trump". Personally I think "50 cent army" isn't as bad as "WuMao" even though they mean the same thing, go figure.

The essence of my analogy was both are terms that denote the ideology of a person, something they CHOOSE, not are born into like race.

If you believed your government was good, why would you care about a label that targeted you as a supporter for them?

Calling someone a "WuMao" is saying that the person is PAID to support the Chinese government, regardless of their actual opinions, and the target of support isn't in the term itself. Calling someone a "trump supporter" doesn't include the part about getting paid.

There seems to be a negative connotation with getting paid to support something, that you're just in it for the money and don't actually mean it.

Of course there are many nuances to the whole issue of labels which I don't have the knowledge or time to go into.
