That’s true on face value. The issue is that accusations of misandry are almost always unfounded, and only made as a way to deflect and to attack women. So when people start talking about misandry, that’s generally a red flag.

It’s similar to how “all lives matter” is definitely a true and good value - but yet it is almost always said as a way to divert support away from vulnerable groups. So although the literal meaning is good, it is fair to assume that people saying it do not have good intentions.
