The impulse that some people have to try to mentally combine everything they like into the same personal continuity while rejecting everything they dislike seems exhausting to me. I don’t have any trouble accepting multiple canons. I love the Thrawn books, but I’m happy to leave them in the Legends timeline instead of going through the mental gymnastics of forcing them into the ST continuity.
Similarly, it always felt easier simply not to focus on the things I dislike than to declare that they don’t “count” and find workarounds to keep everything else consistent. Some years ago, I visited an aunt in Tampa. I did not care for Tampa, but I don’t feel the need to convince myself that Tampa isn’t there; I just won’t go back to Tampa. I feel the same way about Jabba the Hutt’s Truman Capote uncle: if I don’t rewatch those episodes of TCW, his being “real” in the context of SW canon can’t affect me one way or the other. Since the things I don’t like are almost never load-bearing elements of the things I do, I find it’s much simpler to just roll with canon and not revisit the stuff I’m not into.
