People like to make themselves sound smart and important by finding the most trivial and low effort ways to discount and invalidate your point, instead of expending effort to respond to a more substantial argument that I could easily read from what you wrote. It's just the nature of online forums I think. It's easy (but incorrect) to conclude this place is full of jerks, because sometimes jerks are more likely to respond at all, and you don't get a baseline of how many people read your message but didn't reply at all.
