What's a REAL boxing fan?

So I would like to address this issue, so often in these threads and posts I see people saying another person is not a real boxing fan, for whatever reason. Most of the time I think it is because they just disagree with what the other person has posted. I really don't understand this, if you enjoy boxing and you watch the fights are you not a real boxing fan? I don't know if anyone has said this about me personally, boxing has been my favorite sport for over 4 years now and I love it. I consider myself a hardcore fan and I think I am pretty knowledgeable when it comes to the sport. But, I really think everyone is entitled to their opinion, if they have reasoning for giving it. I do hate when someone just hates on a boxer for no reason, because it is kind of stupid. I do really think that if you are on this site and have signed up to make post's then you are probably a real fan whether you are ignorant about boxing or only follow a couple fighters. In my opinion people need to stop with labeling people "not real boxing fans". However, if you got a reason for thinking there are people on here that really aren't "real boxing fans" than I would like to here why.
