Nah it's strong feelings because it's like your mom says she's going to marry that ********* guy and he's now your "dad" and his ********* son is now your "brother." We're supposed to welcome these smiling, questionable newcomers into the SW family without question not because they earned it as worthy additions, but simply because the boss says so (and has some personal interest in it all being "one happy family.")
Well, even if your dopey little sister doesn't know any better and blindly goes along with whatever mom says, you know the family better than even the boss does, so there's gonna be some strong feelings. Even if your dopey little sister gives you frustrated speeches about how it's one big happy family and it's just as great as it ever was (forgetting she doesn't remember and only knows it through old photos) and it's just your shortcomings that makes you not embrace this extended family.
The discussions have mellowed only because TROS divided the divisions. Nobody knew wtf the argument even was anymore. People who hated TLJ loved TROS, others who loved TLJ hated TROS, still others who hated both equally but still liked TFA - it all got so confused that people just threw up their hands and agreed the ST was a bit of a mess (for vastly differing reasons) and walked away.
