It does seem like a good idea to revisit the open letter (and the LSM's response) again in 2023.
The LCM's response is very long and no one has the time to write a rebuttal against all of their nonsense, but I think that their arguments regarding the trinity (only 10 pages long) is of a manageable length to write a rebuttal. I am currently swamped with secular work right now but I will start working on it ASAP.
Wish me luck
