I seriously doubt Dagger G meant any malice towards his opponent in the Guile clip.
Perhaps take a while to actually learn about the personalities of the people you follow before making snap judgements. I've met him many times in person and he's always been a nice guy and hasn't made a career out of insulting opponents in casual online matches.
Player-wise: Dagger G was epic back in the SF3 days, using low tier Remy and dominating vs the best character in the hands of one of the best players of all time, and generally displaying a lot of high level prowess in both sf3 and sf4.
To put it consisely, most fg players will go their entire gaming careers not even touching anywhere near the level of technical skill and ability Dagger G has.
Let this man flex his execution whenever he wants and try to understand what you're seeing or ask questions when you don't understand something. That's how we grow together.
