As I said "I must discern for myself whether or not to risk sinning by not going for whatever reason." I am not trying to tell anyone else what to do.
And remember that in this case, we are talking about a certainly validly ordained priest and the True Mass - nothing whatsoever to do with NO priests and their jazz. I am saying that if I went at all, it would be because it's my one and only choice and that I would perhaps go to confession, receive Our Lord, and leave when it ends. IOW, regardless of his serious faults, I would use him for what I need, for the benefit my soul and that's it, that's all of it. It's not like I'm endorsing conversing with him. I am conditionally endorsing using him for our soul's needs *if that's all you have available*.
Also, I was raised to never look at whether the NO "mass" was valid or not because it is neither valid nor invalid, what it is for sure is evil. The consecration within the NO "mass" might be valid or invalid, no one knows for sure, but I avoid the NO because regardless of the question of validity of it's consecration, the "mass" or service itself is evil, and it is that service itself that brings with it the loss of faith.
As I said, that's how " *I* look at it," that's how I've always looked at it. Deo Gratias that He saw fit that *I* no longer need to concern myself with any of that, but that's how I worked it when I did - and how I would work it if I need to again.
