Lyby, please retry this crossout exercise according to my revised instructions in post # 326. The point is to erase pairs of matching letters.
This is different from the letter-canceling in post 190. PDJT's message there just demonstrates that you can construct a coherent argument about anything that – if the entire text is long enough – will reduce to a single letter by canceling all multiple instances of a letter. In this case, he wrote a message that deliberately only contained one Q, while making sure all other letters appeared at least twice.
