Ah, I see. So falling back on the "you can't criticize something's obvious faults unless you can do better" excuse, are we? Sorry, I don't need to be a professional painter to know when someone else has done a poor job with painting, just like I don't need to be a film director to criticize a bad movie or an architect to criticize a poorly designed building.
The idea that people should only be allowed to say positive and "nice" things about other people's work is the only "toxic as -blam!-" thing going around here, because criticism is how people correct their mistakes and improve themselves. Your attitude leads to paper-thin feelings, an inability to handle constructive criticism, and a false sense of accomplishment. It's why we now have bullshit like "participation trophies"...
If someone can't handle people saying negative things about their work, then they shouldn't put it up for public appraisal.
