Why is it that when a man does not like Amy Schumer, women automatically assume that he does not like female comics in general?

Whenever I read an article about men not liking female comics, the default argument is that the female author likes Schumer, but her husband or boyfriend doesn’t, and extrapolates that therefore he and men in general don’t like ALL female comics.

Why would you assume that if doesn’t like one female comic he hates them all? And why pick Schumer of all women? How come no one picks someone like Tina Fey, Amy Poehler, Carol Burnet, Kristen Wiig, etc? These women have lots of male fans?

It seems like confirmation bias. Women out there already believe that men hate female comics. So when a man voices displeasure at Amy Schumer, that reaffirms her belief that men hate ALL female comics?
