There is a hostility amongst pac fans from back in the day , the reason for it is , that when pac died , there was no question in peoples minds that biggie and or badboy was behind it , none! like 0.000000 percent chance it could be anybody but biggie or puffy or somebody in that crew was responsible , especially since pac was shot by one of biggies friends not long before and the fact that he announced to the world he slept with biggies wife.
Pac was the type of rapper that made a lotta people feel like he was your brother , where you knew if somebody was fuckin wit you even racist cops he would hop out and open fire , risking is entire future on a complete stranger like he did in the past , in a time where discrimination was high and times were hard pac was the only one out there sayin he gave a shit about us , so he connected with a lotta people on deeper level.
So when people come out talkin shit about how biggie was better than pac , its brings out niggas emotions cuz deep down they still hold big in some fashion responsible because their was no closure to say otherwise , and arguing about how big being better is like sayin the dude that killed your friend is better than him , being that you are confronting 2pac fans in the first place , your arguement just based on the music alone is foolish because people done made up their minds about the music a long ass time ago.
Trying to convince someone something they heard doesnt sound great , is like going to a restaurant and spending 20 minutes explaining to patrons that the cheesecake that they are enjoying doesn't actually taste good , that they are delusional and its all in there head , that the steak they had was "overrated" eventhough its exactly how they like it.
Lastly anyone who makes a significant impact on you even if you may have never met them in your life is part of it,maybe for a short time or for the rest of your life, that goes for nas , eminem , 50 or anytype of fan and that artist's importance is to you is dictated by your own tastes and whats happened in your life thats why people still gather at the spot john lennon died on his birthday because they care and are not wrong for doing so.
Truth is if you spend your days trying to convince people that what they like is garbage , your the one who is really delusional.
