I think everyone who supports BCH needs to really drill down into why they believe in this technology. If you don't understand the white paper or why proof of work secures the network by punishing attackers and rewarding honesty - you need to do some digging.
To break people out of the matrix we need to be able to convince noobs and those who are still open minded that the concept of "every user running a full node" is not only a lie, but anti-bitcoin. This is not a difficult argument to win. Usually all you have to say is "if my home node disagrees with a mined block, my home node is powerless to change the contents that block".
I know we're allergic to talking points around here but we should get in the habit of saying the words "a non mining node does absolutely nothing to help decentralize or secure the bitcoin network".
