That's a pretty typical reaction. When someone can't refute the data or facts, to attack the integrity of the person presenting them.
When former Catholics present what they know to be the facts of Catholicism and what they experienced as Catholics and it casts the RCC in a bad light and cannot be refuted, then the charges are laid of vindictiveness, bitterness, ignorance of church teaching, and all manner of personal character failures in an attempt to discredit what they say as being biased or inaccurate.
Since the facts cannot be disputed or refuted, the only option left is to imply that the messenger is unreliable.
That might be true if the person had the integrity to actually post the data or the facts. All you've posted are muddled musings with no evidence to demonstrate what is being posted is true.

But it's when these "facts" have repeatedly been demonstrated to not be facts at all, but are still repeated, that it begins to look like bitterness talking. And repeatedly posting erroneous doctrine after being corrected can only be seen as failure.

The messenger has demonstrated on her own that she is unreliable. For example, we're still waiting for you to post facts regarding the Ukrainians that cannot be disputed or refuted.
I would even go further and assert that the one denigrating a person with whom they disagree is who truly is demonstrating bitterness as well as anger. They are showing an inability to be confident in what they believe and so they must impugn the one they are in conflict with to settle their own doubts about their faith. I'm not a psychologist, but I recognize "projection" when I see it.
