Having different standards for different speakers is exactly what you're doing.
Criticizing how a message is delivered is standard HN criticism. Especially the sort of "everyone is smart except for me" tone of TFA. I myself criticize commenters here for that as it's something I can't stand, either.
Why would you think it's something we only see leveled at women here? And, according to what? And, yes, you're then infantilizing women when OP does receive that criticism. I think your heart is in the right place, but you're doing exactly what you think you're condemning.
