I think part of the issue is defining "unkind". If someone asks my opinion, and my opinion is that there are problems, and I state that opinion...is that "unkind"? The theme of this post is that for ND people, saying "It's nice, I like it" is actually unkind. Because we want real useful feedback.
I have learned to be more aware of people's feelings, which is why I generally dont give feedback anymore. One of the #neurodivergent hallmarks is our social awkwardness - Bluntness being a common trait. But why do some get to make the rules of social acceptance and others don't? Guess what...
...Zero Neurotypicals have ever given a shit about MY feelings. They assume they are being "kind" but they have no clue becaue they are self-serving sheep mindlessly following some unwritten rules and acting as enforcers by shaming those who don't conform to their standards. (Tact? What?)
think of it is how societies "get along". That's the whole "unwritten rules" thing. Avoiding saying anything that might upset someone, hence not going into detail about criticism, is just a "thing" in general society, most of the time. Germany is one exception.
You're taking this in a way it's not intended just like neurotypical people take your kind of honesty the wrong way at times. I don't know what to do with a phrase like "self-serving sheep" because I equate that with people who are usually conspiracy theorists, sorry. A "fakeness", as you might
Unfortunately, in life, the majority of a population gets to make the rules. It's not always fair, but that's just how it is in a modern society.
The way you phrase your opinion is how it becomes unkind or not. That's where tact comes in then. I think feedback, the way you mean it, isn't the right word to use for neurotypical people. What, I think, you should say is, "Tell me what's wrong with this and you don't have to be nice about it."
