Segwit enables 4MB blocks so all this talk about "1mb blocks" is kinda silly. If you don't understand the technology and block weight don't try to make claims.

LN can work without segwit but it works much better with segwit and segwit enables a lot of other things like side chains and shorr signatures etc.

No there was no agreement called Segwit2X. The BCH people agreed segwit2x but the developers weren't even invited.

To call something a compromise or an agreement when one side was never even invited is disingenuous at best.

But this kind of misrepresentation has been going on for years and is the primary basis of attack against core-- because there are no technical arguments against core.
