When smash players of any kind start hating on other smash players, it's not good for the community as a whole. Look at the weeklies at Xanadu, which host both brawl and melee. Those weekly events are fun, successful, and get an online following because of the live stream. That sounds like the sort of event that will help the smash community be sustainable.
Additionally, if you want to bring new blood into the melee scene, you probably would benefit greatly from drawing on the brawl scene for new players. The only reason I chose to start improving my melee game was because CTL came to brawl events.
Food for thought. I won't argue the point any further, nor should you.
