I put him on my ignore list, because he knows a lot, yes, but just as he gives you walls of text about things he is right, he gives you walls of text about things he is not right and he is constantly entrenched in his position.
An example in this thread:
Also:
PLEASE REALIZE THAT franky's ARGUMENTS ARE GARBAGE. As they are based on a former draft on a slightly different subject, that didn't pass,
as I've shown on page 2. And when he argues, he changes your argument and counterargues against something you had not said, which happened to me debating with him before in other threads. So for me the solution was to put him on my ignore list. Without acrimony and without having anything personal against him.
Most of the negative feedback he got is not valid to me.
For me neither, those referring to his opinions or how he argues should be neutral in color, even if they are negative in spirit.
