I don't know why he keeps bothering us here on CathInfo -- is it to convert us? No.
How can I say that?
Because he doesn't act like the Saints did. The saints were zealous and fervent in their love of souls, the truth, and sinners.
They strove day and night to convert them.
But they didn't try to catch flies with vinegar. And they spent plenty of time in PRAYER, FASTING, and CORPORAL PENANCE to convert sinners. That is how sinners are converted.
Read "The Soul of the Apostolate" for more information. We do have to resort to words, actions, and writings -- but they are given unction and efficacy ONLY by ourselves or someone else offering up prayers and penance. That is how the economy of salvation works.
Not by armchair lay theology, ceaseless arguing, calling names (especially cuss words), and other human and base behavior.
Sorry, such a person doesn't pass my Catholic "smell test". St. Francis de Sales knew when to give up and move on to fasting and prayer for an incorrigible sinner.
But that's only if a person is TRULY interested in God and the salvation of souls. If he's interested in himself, "winning" an argument, or some other base motive (such as obsession with a given topic) -- then he'll behave differently...
