Someone willing to visit China probably isn't quite that level of hateful, and if they are, they'll be doing it to just lie about the country (like the youtube "China watcher" white supremacists do.) Having more non-nazi people visit will make it clear to Europeans that their own media's claims about China are just lies.

And the western media's only retort will just be "Don't ever visit China, just trust us on what it is really like and if you do go, don't believe your own lying eyes." which only works on the exceptionally brainwormed (who were never going to change their minds anyway)
