Roe vs Wade has been in legal conservative crosshairs since it was decided. There is no movement by anyone to undermine the prohibition on ex post facto laws. These two things are very, very different in how legally well-founded they are in the eyes of conservatives.

I know this decision is awful for many people and has created justified anger, but this isn't the Anschluss. The people who did this aren't trying to destroy every venerated legal structure in the country to impose their will.

Not saying it's 100% impossible for some crazy thing to happen, your wife's anxiety is understandable, but I think a bit of perspective could help avoid needless panic.

I would also remember that Trump's bid to disregard the election was shut down in part by judges he appointed. Legal conservatives do actually want to conserve the legal traditions of the country, for the most part.
