Yes, he is still an ar**hole.
But you are paying the Instructor to criticise your flying, so that you can improve. Learning a new skill, especially a demanding skill such as flying, will always be difficult. A good instructor will keep the pressure on most of the time to get the best effect of time in the air, but equally they should allow some unpresssured time for you to realise why you are doing it - to soak up the triumph and elation of each new step forward.
Some instructors just have a bad way of passing on this criticism. When I flew in the UAS, one of the instructors had a habit of hitting your hand if you reached for a control when he didn’t think it was needed. Eventually I got pretty scared of doing anything and it really held my flying back and made the prospect of a lesson with this particular instructor very daunting. Luckily I didn’t have to fly with him very much.
But do stick with it - I assure you the end result is absolutely worth it.
