Correcting a commonly abused saying, and thereby slightly reducing the volume of bullshit if only imperceptibly. I have to wonder why you seem so interested in commenting mostly on the comments of others.
In general, though, I feel that the more precisely we use language, the more expressive it can be. Begging the question is different from raising the question. If we allow that conflation, it then becomes more difficult or requires more words to express what "begging the question" really is.
By analogy with Huffman coding, the meanings that are used less often should require more words to express than the more commonly-used meanings. And if you really want to express the meaning "assuming the premise", then you could just say "assuming the premise", instead of insisting on the "precision" of using a 16th-century mistranslation of petitio principii.
Would you mind sharing with me how you would have written my initial comment, (given what you know of my intention) that would have had the most positive effect on you? I'll take my answer off the air. Thanks again for your time and attention here. It's a rare opportunity and I do appreciate it.
