I'm going to include the page where this happened, so that both the line and its surrounding context are present for comparison.
None of this says Lorna was even on Genosha. All it does is show she's aware Genosha happened, and that Magneto was in charge of it.
I could very easily argue that Bunn had no idea Lorna had anything to do with Genosha. That he only knew Lorna is Magneto's daughter and wanted to use her in that capacity to praise his leadership on something he thought she had nothing to do with. If I was dishonest, I could construct a whole case in that vein including scenes from Blue.
Do I think he was hinting at her history? Sure, but you have to KNOW it's a part of her history, something you do not need to do any time it comes up for Magneto. Because Marvel explicitly acknowledges he has that history. Something they never do for Lorna.
I'm not going to let Marvel slip by on a technicality where you have to KNOW Lorna's history and make assumptions that the average person very obviously is not going to be able to make in order to read it that way. That's not good enough. If they haven't explicitly acknowledged it in the same way they've done repeatedly for Magneto, then they're ignoring her history. Simple as that.
My point about the use of "father" still very much applies here. Marvel can have her say "father" in X-Men #1 at least twice, maybe more, but she can't explicitly mention surviving Genosha once in 10 years (all media) or 15+ years (comics)? They didn't even do it in Prisoner X, where they had no issue showing far more obscure scenes, including forcing in one of Lorna kissing Havok.
The only time I would say Marvel's actually acknowledged her Genosha history was the one lone Amazing Spider-Man cover from a year or two ago.
That's the closest Marvel's ever come in 10/15+ years. That's not good enough. This is a hill I'm willing to die on.
