You are driven by emotion, which forces you to not move beyond this term.
That is OK. I do agree with you that a more empathetic term would be fitting.
However I am attempting to keep this as neutral as possible. From observer perspective.

If you were fooled by the posts then you most definitely didn't read them as simple claims in the posts such as "I have been on dialysis since birth" and "I have been on dialysis since 2000" are impossible to accept as non-conflicting.

You are a very clear example of how easy it is to fool the gullible or emotionally driven.
Thank you very much for your input. It is more valuable than you think.
