Daily reminder that the only thing that disqualifies males from fitting every criteria for "parasite" is that "true" parasites don't promote their host's fitness (false and dated idea, by the way). Ecologically, there is only a semantic difference between a human male and a parasitic wasp. Another daily reminder is that the human male's niche in society can't be described as anything other than adult brood parasitism - the female using her finite caretaking resources to nurture something other than her genetic offspring.

The human male is by every measure the most successful parasitic organism on earth. First it uses you to incubate its descendants, then it makes you raise it until it dies of old age, often pursuing other hosts in the process. Just let this sink in a little. What other organism can boast of anything like this?
