Your view that it is easy to determine who is free to remarry and who is not is simply not credible.
If it were we would not need tribunals nor seminarians doing numerous papers in canon law and sacramental theology, nor refreshers for PPs.
Is it so hard to accept that theologically untrained autodidact lay people still don’t have what it takes to fully understand or weigh in on these matters.
Your own continually flawed views continue to witness to this self evident truth:
There are Petrine and Pauline privileges. Once those privileges are consented to, there is no turning back. That is Holy Matrimony.
Please. My validly married Catholic brother would take strong issue with you here for suggesting that he is not in “Holy Matrimony.”
It doesn’t take brilliant lawyers or theologians…it simply takes a comprehensive targeted education from those experienced in these matters.
You clearly are not.
There’s really nothing more to say if you cannot accept the obvious truth of what I observe.
