Why do the supporters of 2X want to risk there on Bitcoin with no replay protection.
Somewhere I feel this is a hoax of some sort.
You can take precautions to that not happening.
If you split your 1X and 2X coins onto 2 different(!) wallets/addresses you are fine.
No replay protection can only be exploited if those 1X and 2X coins are lying on the "same" address (to be exactly: on the same private/public key pair; since it can't be the same address when its on another network).
And as long (after the fork) you didn't send any coins, there is no Transaction which could be replayed on the other chain.
