I specifically emphasized the word "relay" in your reply
And that's the whole point of what I'm trying to convey. If the full nodes (which are only relaying the blockchain or its changes, i.e. not confirming transactions) consider some block as invalid (for whatever reason), the max what they can do is not to relay the changes. In other words, they themselves cannot invalidate the offending block. Instead they would be just relaying the old version of the blockchain (i.e. without the offending block). Thereby, whoever is taking the blockchain data from them will be thinking that they are just sending them the stale version of the blockchain
I wouldn't say whoever is taking the blockchain data from them would be thinking... anything at all, really. Unless "whoever" had actually received the invalid blockchain themselves, they would never have known about it to begin with, so in turn, they also wouldn't know if they hadn't received it (I'm sure I could have phrased that better, heh). Basically, the other receiving node won't miss anything it never knew existed. In terms of "stale", the network as a whole doesn't particularly care how frequently it receives updates or how long it takes. As long as it's valid
With that I can't disagree (you certainly might have explained it better)
I read your post a few times (I admit that my head right now is filled with different things), and I couldn't get a clue what you are talking about (but it kinda looks like a tautology to me). In any case, you still didn't address the issue which I raised in my previous post, i.e. full nodes not relaying invalid version of blockchain (as they think or what their software "thinks") would be irrelevant since they are just relaying what they have been relaying before, i.e. the same blockchain without the offending block (as if this block didn't exist at all). In this manner, they don't contribute anything to invalidating the wrongdoing of some rogue miner. As I get it, only other miners can do that (by means of excluding such a block from their version of blockchain when they find a new block)
