Absolutely. The details do seem to surprise people, but I think that's because they're often elided in euphemistic summaries and don't stand out in someone's profile history the way that trolling and right-wing invective often do.
It's not like they're all-caps yelling about gas ovens, they're just politely welcoming people into their instance and occasionally upvoting or suggesting that wellactually everything's fine in XinJiang and it's racist to believe Uyghurs who say otherwise, etc.
