Every day, we state facts briefly. You might say "That man is a criminal." You don't cite the cases and details.
.....
Anecdotes are not facts... you are still wrong, just stop with your nonsense
.....
Not an anecdote. Saying "That man is a criminal" is stating a fact.
It's true, another party might say "I don't believe it. Prove it." Then it's incumbent upon the first to state the underlying details.
Just go attend a chemistry class. Nothing but exposition of facts without underlying support. All of science is this way.
