I think it's easy to be irked by someone downplaying your dedication/work put in to something you have and use well, whether you were born with it or not. Probably not as easy as it is to irk someone with really good sequencing and technique whose body isn't capable of doing what others' can with half their efficiency. Natural speed, strength, and hand eye coordination absolutely plays a role.
I wouldn't blame you. It doesn't matter how much natural talent one has, nobody gets good at this game without a lot of work, even though the opposite may be true.

I have no business posting in this thread, but I will say as an older guy (59) who never had power at any sport - even in my prime - the fact that I'm now averaging the yardage of most male amateur golfers with my 7i leads me to believe that I'm doing something right, even with my goofy-looking swing.
When my son was pitching in high school, we would play catch every night after I got home from work. He was learning some very good fundamental mechanics to increase velocity. No matter how hard I tried to use them, my rag arm was incapable of any real increase. I think power is a combination of ability and technique.
