Furthermore placing our trust in the Core development team is a far more dangerous form of centralization then compared to anything else that is within the Bitcoin XT client.
Distrusting XT or BIP 101 =/= trusting the Core development team. That's another blatant mischaracterization that keeps being throw around. Please keep the discussion honest.
You're doing a good job arguing your points successfully, but I don't know whether engaging people who are happy to present such willfully dishonest arguments is genuinely productive in the long term. It suggests that these people and the arguments are worth addressing. Unfortunately the dishonest arguments cannot be separated from the others of a single participant, but we could separate those participants who use dishonest strategies from the debate. I don't address them.
