Hate is a powerful force to be used with prejudice and Disney era canon is a powerful conduit. I'm pretty sure I barely exist if at all there so you can imagine my preference for Legends is strong.
But yeah, I guess Disney canon is not out of line for the modern generation and I've actually seen it turn over new fans for the old expanded content. From time to time I do find things to like. Rogue One, Andor. I'm tolerant if and as long as we see more of these. There's just enough passion for Legends material for that to be kept alive, slowly. I've toyed with the idea of a campaign mod for Jedi Academy based on the very old republic with themes from KOTOR. So the dream is alive and Disney has done better than other companies in letting you eat from both pies. Star Wars has always had the benefit of offering different things at different levels to enjoy, heck, that started with Originals vs Prequels. Compare to, I don't know, Blizzard Entertainment where you see hopeful older material and it's totally overwritten, and overtaken by newer, not necessarily better material. Far harder to find common ground.
In Star Wars you have many fragments but that means you can always find an aspect you can discuss with someone who's deep enough even if you have passionate differences with a particular form - the clone wars animated series, originals/prequels/sequels, old republic era, books from various timeframes... even if you divide on Canon (disney) vs Legends. I can't think of another setting with this sort of reach.
Also I've always been more old republic style than anything else and it's not been heavily touched by modern Lucasfilm. Their foray is easily isolated into one era while I can pursue others. I've never been terribly interested in what happens post ROTJ and the sequels helped put that to bed even more. So I find it easy to just live and let live on this subject. If you like modern canon, great...
