The lack of strictness in English means you can say something wrong but intelligible very easily, so we all get by.
By the way, it shouldn’t matter at all what a linguist thinks about that unless it is literally his field of expertise. And political sociolinguistics is not a field of expertise of most linguists.
Yeah but do they? It doesn't seem to me like a standard of this kind is anywhere near a priority for anybody. I'm not even a native speaker and I never felt the need of it. Why are we trying to fix something that's clearly not broken?
Traditionally, begging the question is the logical fallacy of assuming the consequent: proving that something is true conditionally on the fact that it is true and then deducing that it is true.
It is a mistranslation because it’s origin is a poor translation of assuming as begging and the consequent as the question.
On the other hand any direct translation (and initially translations were direct translations through several languages which is worse) of any early works of philosophy or logic (say Plato) will have this problem as the vocabulary Plato had to use just didn’t already have words for all the things in logic and philosophy that we now have words for.
I do occasionally cringe at changes to English driven by the great influx of non-native speakers and lack of education of even the native speakers, my favorite being https://en.wikipedia.org/wiki/Begging_the_question
But hey, it's all good. This is how culture changes language. It's a living dynamic.
