> Was Donald Trump leading a violent group of traitors and looters to desecrate the capitol, or did he and thousands of others peacefully protest against the Democrats stealing the election?

Neither of those is a matter of fact, but rather interpretation of the facts. The facts are that Donald Trump posted on social media encouraging people to fight the election results (or something to that effect, I don't have an exact quote to hand), and that a group of people were protesting and then went past the security barrier to enter the Capitol. You can interpret those facts in different ways (as your question shows), but either interpretation admits the same facts.

As one of my favorite youtube creators, Feral Historian, put it: "Most of the time, people equate the facts and their particular way of connecting them. Most political arguments are about the lines, not the dots. We think our opponents are ignoring the facts when they're just seeing different relationships between them". I think he's spot on with this observation, and one must be extremely careful to delineate between objective fact and the conclusions one draws based on facts. The latter are not objective, even if we feel very strongly that they are obviously correct.
