It's frustrating because we have a real issue with spoken communication where explaining anything that isn't super simple might stump us for a while because we've had the problem of trying to explain "advanced" stuff with the assumption that that's the base level of understanding one needs to explain the more complex stuff and on the other end she's said out loud "do you know what an input (in the context of a button press) is?" because we didn't even know where to start.
So it is extra frustrating to get some rando comment with "I disagree. [WORD SALAD FOLLOW UP]", reading it three times, being totally unable to parse what is being communicated because it is extra frustrating when you realize they are not putting in the effort to communicate effectively. This is not us being thick or having a brain fart, it is literally nonsense and irrelevant to the conversation.
