People need to learn how to argue with these factless people:
There were 30,000 deaths. The right wing is lying to cover up their crimes.
They offer no evidence or justification for their claims, so if they accuse you of lying just ignore them and keep saying the truth.
Trying to explain how there were 22,000 tracked deaths 5 years before the end of the regime so of course there were at least 30,000 but not all were documented is beyond the mental energy of a lot of people.
The regime killed 30,000. If you deny it you ask for it again.
