once you have researched what they all actually are.

You yourself have no idea what they all actually are.
Interesting assertion. I'd like to read your extensive code review of each such "other implementation".
There isn't an extensive code review of such an implementation by myself (probably not by anyone, as I haven't seen one). That's not the point though. The point was that 'these people' are throwing around assertions regarding the safety of random block sizes just because 'it's fine one some test-net'.
You do, of course, realize that if one lonely cpu starts mining upon this chain, you will have been proven utterly wrong?
I was talking about the current miners of Bitcoin.
Oh wait - self-contradiction in one neat paragraph - quite an achievement!
It's not a contradiction; read the above.
Well, no. Segwit does absolutely nothing to make larger blocks safe.
Yes, it does actually, since there's no such thing as "The SegWit Omnibus Changeset".
