This one really stood out to me, because it seems like a very oddly specific complaint. I don't know when people accused you of "violating good faith", or who accused you, or why, so it's really hard to tell. That said, it's certainly a thing which is in at least some cases not even a little bit either "respectability politics" or "tone policing". There is a significant difference between arguing with a person who disagrees with you, but who distinguishes between true and false claims, and arguing with someone who will say absolutely anything if it seems to advance their cause right now, and they don't care whether it's true or not, or whether or not it contradicts things they were saying five minutes ago. One of those situations admits the possibility of progress. One doesn't. More generally, a whole lot of your analysis here makes no sense unless we start with the presupposition that "Kintsugi" is a monolith and that "Kintsugi" can reach an opinion on things. I don't think that makes any sense. It also seems to just sort of ignore contrary evidence.
