The bolded sounds like typical victim complex.
No one is "looking down on him". Just because someone views another player as better than Matthews doesn't mean they're looking down on him. If someone says Gretzky is better than Crosby, I'm not going to cry "why is everyone always looking down on Crosby?!!" because I know that they're simply choosing who they believe is the superior player.
As for why there's a focus on points and not just goals, it's because there's more to being an overall superior offensive player than just who scored the most goals. Otherwise, Ovechkin would have won the Hart and Lindsey for the past however many years in a row he's won the Rocket.
