There is absolutely no need for instructors to shout or use the F word in a derogatory way to their students.
Some bad, shouty instructors get away with it NOT because they are popular sky gods, but because students are naturally going to be nice to them, since they might be signing their papers.
Spoon feeding: When learning to fly, there is so much information, a student does need someone to give them direction and focus. They cannot expect an inexperienced student to always know what to read up on. One function of the instructor is to guide the student through what is important and what to go into detail on. A reading list and a study plan ideally.
Students in the early stages are usually paying the instructors wages, so they should not put up with poor instruction or a bad attitude from the instructor. Easier said than done sometimes, but don't put up with it.
Good luck to the OP, whatever you decide. If you want to go into upper atmosphere/near space, the Mercury, Gemini and Apollo astronauts were mostly former military test pilots with degrees, I think?
