SMILE WHEN YOU SAY THAT–I
It is not necessary for a reenactor to provide provenance for something he says. It seems to be a requirement only if you care about facts. And many reenactors, looking for the easy way to their beliefs, it is not required. It could be made by a reenactor who is considered so infallible that their word is the only thing needed.
I cannot count the times that a reenactor makes statement that goes against what I have uncovered and, when I ask them about provenance, they simply do not answer or repeat their statement, far louder and more adamant but with no more provenance than before. In fact, many will seem irritated or offended that you should question the veracity of their statements. They do not say that above paraphrase of Owen Winster’s “When you call me that, smile” out loud, but it is one of those times when you can almost read their thoughts.
Ask for provenance. No, demand it! Sometimes it works, and you learn something that you had not known. But if the speaker refuses to supply provenance, let it drop. Just never repeat or believe the tripe he spouts unless you find provenance from another source (which is sometimes you always try to attain in these cases. Getting the provenance from him or another is only the easy way to do things!). If the theory is interesting, you might even resort to saying that the reenactor says this, but you have doubts about the veracity.
Do not think that they are evil entities just because their interpretation of what is a fact is totally wrong. After all, it is a proven fact—I am being ironic here, of course—that when you are doing something that is delightful to you and you are smiling and enjoying yourself, and you discover something being said that you think is really really neat and contributes to that feeling even if it is not true that can be easily ignored. After all, having to find facts that are true can sometimes be very disappointing and discouragingly sad to you. After all, it might go against what you happily believe. Therefore, many “researchers” will just announce a “fact” whether it is provable or not, and just go from there.
It is far easier to find something being said or written that you agree with and use that as your provenance instead of coming up with something that you dislike, that does not support your thesis and that is usually much more difficult to find. It is easier to find something that agrees with your politics or religion or something else you agree with and that goes against something you disagree with than to seek out something that goes against what you think. Research is not always easy personally as well to find.
