All men either consciously or subconsciously crave for authority over their environment, especially over their peers in the society, male and female alike. Women on the other hand, crave for intimacy especially from their female peers in the society. Colloquially this is what you call “gossiping”.
Even though the advocates of feminism gladly use the term to refer to equality between man and woman, the common human brain is not capable of perceiving such equality beyond the gender bias of the very word. It'll be same as using Man to refer to both genders. Hence, the only words suitable in this scenario are Humanism and Human, rather than Feminism and Man.
