No, that's not quite what I'm saying. I don't equate constructive criticism with looking down on others. I think in today's culture, there's no room for negative opinions. If you're not telling someone that "they can do it!" or "you're awesome", you're a hater and not being helpful. As the result, no one can take it. They try to point out your own supposed faults to connect them to the feedback. So, in the end, you're better off just not saying shit.
