Or SEMIVAC for the sedeimpoundists.
Save your money from the extra fees on the personalized plate. Find a good old-fashioned Dieu Le Roi decal instead.
I already have a TLM bumper sticker on my car. This is something I may not even do --- as you note, it does cost extra --- just an idea I've been mulling over.
I have not gone sede because, at the end of the day, I can't make that call either way, and there are compelling arguments on both sides.
Somebody has to be wrong --- Francis can't be Pope and not be Pope at the same time (but then there are the arguments of
formaliter-materialiter, "not quite vacant but not quite full", sedeimpedism, and so on). IMO the strongest argument against SV is that of "(near-)universal peaceful acceptance", but I'm not sure how that applies if you have a putatively valid Pope on the one hand (Benedict, so some arguments go), still in fact the Pope until he died (ditto), and another one elected, albeit probably irregularly and possibly invalidly. And as to what happened when Benedict died, I just don't know.
Just being brutally honest, I would then be looking at the prospect of seeking out only
non una cuм Masses, which are hard to find (at least in the part of the country where I live), and I don't seek to get a debate or argument started, but I'm still not convinced that a sedevacantist should be attending
una cuм Masses (or that a sedeplenist should be assisting at
non una cuм Masses, though I find a weaker argument for that, in that IMO omitting the name of the putative Pope makes no direct assertion one way or the other). Might as well be honest and say that's a factor for me.
So I just don't know. I am at peace in the knowledge that this is a call I don't have to make, and I just live my Catholic life as though Francis doesn't even exist. Nothing he says or does that is contrary to the Faith can bind me. It may be fence-sitting, but I can't see a way clear to do otherwise. I'm not going to get into a back-and-forth SV-SP argument here, as it ultimately resolves nothing.
I am quite aware that opinions are all over the place here on CI regarding this issue.
