If Illuminaughty was a libertarian, they wouldn't give a crap whether the Flames marched in a parade, visited sick kids, or did anything aside from hockey. Given that isn't the case, I'm dubious of the claim.
Possibly unpopular opinion time; Illuminaughty is right to a point; marching in the pride parade
is totally different than visiting sick kids.
Curveball time: I think the Flames participating in the Pride and showing support for LGBT equality has a much greater impact and is far more beneficial to society at large than visiting sick and/or terminally ill kids.
That doesn't mean I think they should do one over the other, or 'stick to hockey'. Both are important and they should continue to do both if they so desire.
