I can't speak to numbers, but archbishop Lefebvre told people they could attend the new mass FOR SUNDAY OBLIGATION if they felt obliged to which is a lot further than anyone here is even arguing for. I've never heard any traditional clergy EXCEPT fr wathen say you can't go to a new mass for a funeral or wedding. Now there probably are some, maybe they're correct, but that's definitely not a requirement to be a traditional Catholic just because you say it is. Your accusing everyone who disagrees of bad will is uncharacteristically dimondite as well.
I heard many different priests both from the pulpit and in person tell us we cannot go to the new "mass," mostly prior to the 1980s but when the changes first hit, many (not all) of those priests who were kicked out of their rectories told us to avoid the whole NO like the plague that it is. I was too young then to fully understand why, but did end up figuring it out by the grace of God - but now, after all the devastation the evil thing has caused, it's easy to see, or should be imo, yet people STILL defend it not knowing or accepting what it really is.
I sometimes wonder why the trad clergy of all ranks devote so little time to this issue when it seems they should do everything they can to wholly condemn the evil thing, loud and clear, regularly. Perhaps to them it's yesterdays news, but too many of them believe it's only an inferior service.
