I'm the moron? Do you understand what context is? Let me run you through it:

Person 1: "Reddit why you gotta be like this, this was decent"

Person 1 is asking why reddit has to be upset at this woman's singing.

You: "bc its reddit. when reddit sees a woman doing something she's either genius wife material or a used up annoying dummy."

You reply that reddit can only think of women as either wife material or a used up annoying dummy. Obviously, you aren't implying that the people criticizing her singing are calling her wife material. Therefore, by your own logic of "(reddit) men have very black and white opinions about women" the commenters with a negative opinion of this woman's singing are treating her as if she's "a used up annoying dummy."

I think that's fucking dumb. It is very possible to criticize someone's performance without looking down on them as a person. To imply otherwise is stupid, and really makes me think you're just a fucking dumbass.
