Ummm....the "accordistas" don't support the New Mass or attend it. Least not any of the ones that I know....your attempt at a comparison is a little stretched IMO.
How can you be so sure?
Are you an Accordista?
Many of them say the same things as Fr. Arthur -- that we can't be outside the Church, that the Church can't, de-facto or otherwise, promote a defective Liturgy, etc.
I have met plenty myself, and many of them are much more tolerant of the Novus Ordo -- when said reverently, of course -- than the average CathInfo member.
Fr. Arthur doesn't PREFER the Novus Ordo; he wants to be "in the Church" at all costs, and he disagrees with the SSPX "recognize and resist" position -- he basically wanted to switch to "recognize and be as conservative as I can".
