Well that is exactly it it, Datun. Clearly the MO by the TRAs on the hidden thread was to broaden the definition of 'misogyny' so as to make it entirely meaningless as a description of anything specific. One of the ways they do that is by throwing out jargonized terms like 'kink shaming' et al, to derail any useful focus.
For some TRAs I think the motivation for doing this is to be so wide with the definition of misogyny that people with certain proclivities towards validation can be included, whether they are of the female sex or not.
For other TRAs it's so that the application of misogyny is so unworkable, hatred of women can be completely unchecked.
Sadly, in practice, there doesn't seem to be a hair's breadth between these two motivations.
