Rainah said: "Ugh I am of two minds with this. As a bisexual person who was just starting to come out when I saw the show... I loved Lucas, and still do. I love how it's just blatantly said at the beginning, "Lucas has always dated men and women" and no one plays coy about it. Lucas is bisexual. Lucas is also fantastic and has two fantastic arcs in the show, and is really the second most important character after Elizabeth.
That line falls flat to me and always has. If it was meant to be taken seriously, it should not be there. If it was meant to make the audience disapprove at the character spouting something so ignorant, then the narrative needs to do a better job of condemning it. I 100% support characters saying offensive or ignorant things and I think it can be a very powerful piece of characterization, but the narrative needs to somehow drive home the fact that the character is not correct. Yes, a little more forcefully than I'd ideally like, as there are still a large portion of the audience who will be nodding along and thinking she's right unless it's made very clear that she is not."
See, that's my thing. I get that characters say problematic things that express their flaws, and that's fine. But the way the show presents the line, and the way the audience reacted when I saw it (by laughing and nodding in agreement, as you said), shows that if Elizabeth was supposed to be portrayed as in the wrong there, then it wasn't made clear enough.
