I have no beef with them, i didn't even knew they existed before today, but any group that is against all of the aforementioned groups (which I personally am a part of a lot of them) is just a terrible group, not differently then many religious or political extremist groups.
Also, as it states in the next paragraph of the Wikipedia article they are connected with far right politician and Qanon, which doesn't gat any positive opinions from me.
The reason for why they are persecuted (in my 5 minutes Wikipedia search opinion) is not because they are special in any way, if not that they are kinda popular, it's that (like many other political groups, and not only the more extreme ones) the CCP doesn't like them, also the fact that they are against the CCP itself, as it is stated in the Wikipedia article probably is a huge factor.
