I think what he means by concise is use less technical objective evidence, you know the sciency stuff. Take a look at his posts for example, pithy vapid rhetoric, that’s what he wants, leave the facts alone, or just present them with a sweeping one liner, that is facile to the point of mendacity.
Like his “all beliefs are subjective” line, brilliantly concise, and in a sweep it implies the shape of the earth is as subjective as your favourite colour. No one wants to know it is a false equivalence fallacy, christ almighty you might as well be using Latin.
Oh and if someone presents complex scientific data that doesn’t support your position, or even if you are not sure, just label it scientism, and roll your eyes at their “bias”.
Sorry I have used up my irony reserves now, and will have to take a break.
