I think that you might be mistaken.... Having fans with strong opinions and who want their teams to display a certain brand of football IS an expression of support and passion for their team. I think that having an impassioned view of the team even when they play poorly and being content with 3 points knowing that they are underachieving on the field is simply indifference.

We all love Juve.... Rain or shine, wins or losses, goal gluts or goal droughts.... Let us all learn to feel free to express our opinions, impressions and desires for the team with the same fervor as we have when we watch them on the field

Yes I agree with you about fans having the right to express a strong opinion for their team, I would never argue that, but I do believe that constant negative strong opinions lead to negative outcomes

An opinion is neither correct nor mistaken. So who is mistaken.... I reserve my opinion on flowery emotional speech. Being a negative whinny fan of any club doesn't sound like a fan of the club at all. Being supportive by being negative or a downer doesn't make sense either. Maybe its the difference between being just a fan and a true supporter of the club. Just enjoying my freedoms, thanks for the life lesson

Having negative opinions about a team you support doesn't mean you aren't a fan. You just notice that and say it if there's something that bothers you about the team
