Oh but it alters yours. You have no credibility.(And no humility when found to be guilty of calumny). Your attitude is, "oh well this lie didn't stick, I'll just keep trying some others." You spread lies with no concern for truth, why would anyone believe or even listen to what you have to say again?
There is no obligation of humility before the schism and its mouthpieces and adherents. I have already indicated that any error (I am not certain there has been one and I will look elsewhere than the scism itself for proof) but ONLY error is withdrawn. The SSPX schism is still a schism and its ringleaders are STILL EXCOMMUNICATED (as they well ought to be until they have publicly repented and groveled and done penance appropriately) which does not render them or their gullibles trustworthy.
