The FDS community is a reaction to the toxic abusive behavior perpetuated by a lot of straight men in society, which is a real problem and thus they aren't as bad to redpillers or incels who think it's unjust that women won't sleep with them. There is legit and helpful advice to be found there, however the community is also an overreaction and thus half of it is just buckwild. Like there are posts about men who have committed heinous shit mixed in equal measure to posts about how said behavior is caused by bad genes and DNA, and that women need to practice "good breeding." They are also radfems, and like many radfems for some reason, are TERFS; before it was banned the subreddit GenderCritical had a massive overlap with FDS. There's also a lot of classism, since their definition of high value "males" and women is tied up with wealth, and ableism since they advise against dating people with any mental health issues and throw are the r-word. It's basically doubling down on patriarchal gender norms (men must be the primary providers and gift givers because those are masculine traits) to own the patriarchy.
