Not at all. Segwit2x is a compromise that's fine by me. Activate segwit then increase block size. It will result in some increase of miner centralization, but not to the extent that 32MB blocks like Bitmain wants would.
Answer me this-- if it's opposition is UASF, why did bitmain, after Segwit2X got so much support, announce they were going to hard fork anyway?
The Bip148 crowd is happy with Segwit2X because it effectively activates the UASF represented by Bip-148. We don't really care which of the BIP mechanisms is used to activate segwit if segwit is (And I think they are changing 148 to activate along with Segwit2x so there's no split in the support between the two.)
HERETIC
No really, this is exactly what Segwit2x is doing, but it is still heresy for the UASF camp.
