I've never been to any event that star wars fans aren't welcoming. The overwhelming majority of fans are not toxic at all. I've been to comic-cons, toy shows, brickworld, star wars weekends, star wars nights at various events... Everyone has always been awesome. Yes their are toxic fans, but every fandom has them, even walking dead.
Well it's hard to compare because Lucasfilm has not really been all that willing to listen to the fans. They've been more antagonistic with the fans than anything. They've done a lot of blaming the fans instead of listening to them. And while it's been better with Favreau and Filoni, there's still a lot of resentment from the fans for how they've run things. But theres a difference between being unhappy with a direction, and being toxic.
This is why I think your statement isn't really fair. The people who don't care, the loud mouths on the internet, the people harassing actors, they aren't fans, and like you said, don't care. So why do we keep lumping the fandom together with these people? Most are anti-Disney so therefore they will be against anything under their control. Just because fans don't agree with how the sequels came out or how Kennedy has run the franchise, doesn't mean they're toxic. Why does it seem the walking dead fans are better? Because comparing that and star wars is pretty apples to oranges. Star wars is the highest profile fandom in the world. If someone says something toxic about walking dead, it doesn't get blasted around the world at light speed like star wars. It's just not a fair comparison in my opinion.
