Here's the thing, just like my comments you can ignore them.
There will always be more Leaf content on the main boards, whether that's player comparisons or just general topics about how great the Leafs are.
Along with that there will always be lots of threads about how crappy the Leafs are and how their fans overrate their players and teams.
Pick and choose which threads you wish to discuss of course but complaining that they exist will certainly not endear anyone to your cause, nor will it change how HF does it's business.
