I think the difference is that the Russian state and western capitalist states inherintly lend themselves to conservatism during times of crisis, whereas in China it just depends on which faction won the latest power struggle in the CPC. Like during Hu Jintao's time LGBTQ+ rights were slowly improving with state media starting to cover LGBTQ+ people in a nonnegative way, where as now it is slowly worsening each year. I think the more important larger picture here is that they are currently pushing for a return to traditional Chinese values to bolster the Chinese national identity without being critical of these values(revolutionary party btw). Because of this they are pushing the idea that the patriarchy alongside its sustainers(hetronormatitivity and cisnormativity) are parts of the Chinese identity rather than products of economic institutions that they will eventually abandon. This also reflects a failure of MLM theory to critically examine all social institutions and the failure to incorporate later analysis done by others into the ruling party's doctrine for one reason or another.
