One of the things I’ve learned about the consequences of bullying is that when people tell you things like “I’m pretty bad at math” or “computers aren’t for me” or “I don’t really get art or fashion” and you talk to them for a bit what you often find - not always, but often - is what that really means is “somebody treated me like shit for trying to like this when I was 9.”
@mhoye Computers is my bag, and whenever people say they struggle with computers, I talk about how the problem is not them, but the computer systems.
The systems are not people friendly, often. They are geek-friendly (sometimes).
And believe me, I have seen tools that make techies want to try something else too.
So often - in all these areas - the problem is not that "I don't get on with this" - it is, as you say, someone has dismissed their problems, not tried to adjust for them.
