This forum seems to be plagued with "group think" and it is being enforced with censorship. I created a thread called "High transaction fees and how it could limit the growth of Bitcoin and it was deleted. Seems that one thread was a threat to peoples "confirmation bias".

This is just a confirmation bias support group and it is terrified of info about high transaction fees. That is the real fud.
