The Church makes the Laws, she can dispense with her own laws as she sees fit - in this case, she tolerates it for the sake of honor or civil office, other than that only the bishop may (or may not) dispense from the law. Again, this is the Church's law, we are solicitous for the law, and unless this is the way you look at it, then you will never be seeing it as the Church sees it, which is why it does not make sense to you.

Blasphemy, sacrilege, etc. are breaches of Divine Law, which the Church can't dispense with. Your bishop can't turn a mortally sinful blasphemous attendance into a non-sinful one. He just determines which it is and grants or withholds approval depending on whichever it is.

All this said, Pax can obnoxiously call me (and most trads) non trads if he wants,

This doesn’t apply to you because you’re a convert and learning.  To others, it does, because they should know better.

Tradition was founded on the principle of avoiding the new mass at all costs.  If one makes an allowance for the new mass (and many do), then they aren’t real Trads (and many aren’t).   This is proven by the fact that many “Trads” don’t find the indult TLM objectionable.  Why not?  Because they don’t grasp the evils of the new mass; they don’t understand why Tradition was ever started.

If you don’t understand/agree with the purpose of a movement/organization, how can you be mad if someone says you aren’t a true member of it?  Anger just comes from a guilty conscience.
