This is a hockey website, where people talk about hockey. If Johan Franzen isn't doing his job, the hockey fans on this hockey website may use hockey language to express themselves. It may be vulgar - but its nothing personal.
Although it may look hypocritical, you can't fault the fans for eventually supporting him (on a personal level) considering what's currently happening to athletes who suffer from chronic traumatic encephalopathy. Franzen's situation is more important than hockey, and I think the people who realize that have changed tune quite a bit.
That being said - if the doctors say Franzen can go, its ultimately his decision to return to the ice. If he does, people maintain the right to criticize him if he isn't playing well. That's what $43,500,000 gets you.
I understand shouting at the TV in the privacy of your home when a player doesn't perform. Anything goes.
I understand ranting among friends in a private setting when a player doesn't perform. Anything goes.
Taking the time to compose and post a message calling a player a "homosexual" on a message board where strangers, children, and quite possibly actual homosexuals can visit is oafish and dull. Use your adult words. Act like a decent human being. Slurs are best left to middle school boys who think using "naughty" words makes them cool.
