IMHO you’re right! It’s not (only!) about sexism, they make it themselves to sexism. It’s more about the image that only ugly fat nerds are programmers and someone beautiful just doesn’t fit in their little minds. Usually no one fucking cares what people like these think, but because of social media every eye is on those fucking desperate idiots and people feel the whole society thinks like this, what is completely wrong. To say that this is only coming from sexism is completely bullshit imho. Of course there are some, but it’s not the only reason.
