It is entirely true that life is ultimately meaningless and that you are a gene dispersal unit. There is no logical counter argument there.
That's not your entire worldview though, just a small part.
Also, some people would argue for a form of group/multilevel selection theory of evolution which could contradict that. It might not always be your genes that are necessary to be dispersed.
Empirical evidence based knowledge is entirely objective.
Then why are there often competing scientific theories based on the same empirical evidence?
Also methodologies are often required to gain knowledge from information, and choice of methodology isn't objective.
In fact most scientific theories are not overturned, they are modified and expanded upon.
Which still means they were not true in the first place.
I am the highest moral authority. Since all morality is subjective.
And your values are based on a subjective narrative and are thus harmful according to your criteria.
A narrative can't be judged harmful based on truth value, only by some other method such as its resulting effects on behaviour and their consequences.
False information is disinformation, by definition it is harmful.
They are not synonymous, false information may not be intended to deceive.
Where is your empirical evidence for everything false being harmful though? Can you point to some research which demonstrates this 'fact'? Even harm is a subjective value judgement.
Yes all narratives not based on objectively derived data are automatically false.
No problem with that. We all follow false narratives in that sense.
If you think you are exempt from this, that's a good example for a false narrative you follow.
