I don't disagree that comment OP could have phrased it better and come across as less judgey. And I think that of someone like you left a well worded reply to the effect that it would be very fair feedback.
At the same time I feel like some of the comments she has gotten are living down to the less generous version of her statements. If that makes sense. It also sort of feels like people wallpapering over the underlying reason that many women look for social media participation, which is as a way to vet for safety reasons.
But I agree, it's not good to typecast and overgeneralize, and a better suggestion to the post OP might be that some women look for social media accounts for safety reasons, if that is part of your social issues mentioned.
