What should explaining the Catholic teachings require patience? It only requires time, but I am finding some.
Exasperation comes from the expectation that your conversation partner will say “Ah, now I understand and convert to Catholicism”. That will never happen on the thread. Much later, — perhaps; but you are not likely to hear from him if it happens. Write for the anonymous reader, not for the heckler that made it his hobby to contradict the Church.
That is awesome advice and I am humbled by your wisdom. Thank You.
