Well, Ralf, understanding what one is learning is kind of the goal. Learning and understanding is synonymous with a study. There are scholars, apologists, historians, and researchers who spent years and an entire career. My spending 8 or 16 hours of reading and pondering is nothing.
Ralf I typical "study" 2 or 3 hours a day on something, either reading of listening to audio formatted text. I commute over three hours each weekday, so I take advantage of that time "studying, " and I enjoy it. And with the technology today, one can do so pretty much free of charge on a smart phone.
This is just another admission by you that you do not read or study things you criticize and/or champion. I think this kind of approach to learning is where "spoon fed" is derived as description of certain folks. I will continue to give you cf with my assertions.
