@Appleblossom, not sure what you are asking but I can empathise with your son...
Can I start by saying I loved my Dad and believe he loved me... and I believe any of Dads parenting shortfalls (or my perception of) were the result of how he was raised and he was doing the best he knew how.
I can empathise with your son as my dad used to often scoff and mock me, I can't remember him ever saying well done or anything similar, only ever that was not good enough or what a disappointment I was.(Apparently he used to spout on to everyone else how fantastic I was).
I rarely got angry or aggressive back though in my interactions with Dad though, just internalised my feelings which was not healthy. My lack of fighting back and standing up to my farther was due to the emotional hold he had over me. over 12 years since he died and I can still feel that control and see the disapproval in his expression, then feel guilty about thinking poorly of him :- (
The consequence of all this is that I struggle to interact with my own boys the way I would like as I have no example as a reference around how, but also that I don't deal with conflict at all well.
Don't know if that answered anything for you but happy to elaborate where I can if you think it may help
