If you think ‘get a girlfriend’ is some deeply misogynistic language indicative of how terrible the patriarchy is, you need to get some perspective.
This was a throwaway joke about struggling to find a girlfriend. There is nothing toxic or dangerous going on here. They’re not blaming an outer system. Lots of men do genuinely have problems getting the confidence and self esteem to approach women, calling them whiny assholes is not very helpful.
