I'm with you. I didn't have too many issues learning it. But I also didn't know other CAD software, so I'm sure that plays a big part for people; knowing what you want to do, but not being able to find it can be very frustrating, especially when what you want to do now requires an unfamiliar workflow that looks from the outside unnecessarily complicated. So I can understand people's dislike of the software.

I differ on recommending MangoJelly though; video can be good for learning CAD, but I got real tired of having to sit through a 15-40 minute video before getting to the point of what was being demonstrated. I would much prefer written tutorials or pages describing the specific feature I'm trying to use/learn. The FreeCAD wiki was more useful to me than MangoJelly's stuff and I hope people don't forget that it's there. But many folks like his approach, so do what works for you.
