Frankly I missed that in the flurry of temp bans and insults. The analogy works well both ways. I don’t think people consider that this protest was designed from the beginning to be respectful to the flag. It would have been just as much of a protest if he’d turned his back on the flag, or raised a fist at it, but unlike kneeling, those would be considered disrespectful. He chose a different way of showing respect as a means to demonstrate his protest. “A meal fit for Jehovah!” was meant as a compliment.
…but the larger point was very different. Knowing that the dogma exists as a firmly-rooted core belief every bit as sincere as religion, it seems pointless to minimize it, and unhelpful to ridicule it.
