Been in bitcoin for years. Each time there is an improvement in protocols there will always be FUD. But it will be good to look above the technical issues and see the basis of how bitcoin works: a community that supports the development and use of bitcoin. And as long as they support and sustain btc, it doesn't matter how many hardforks occur.
Here's the problem. Core developers (most Bitcoin developers) don't see it as an improvement, and actively oppose the fork. So, if the Segwit2x team and the miners/businesses backing them really move forward with the fork, then the FUD is warranted.
This isn't like a soft fork where a simple majority of miners can prevent a split from occurring. A hard fork "upgrade" requires that every user installs new software and joins a new network. That means a split is guaranteed already. Add the fact that Core and many BTC users don't support Segwit2x? Get your popcorn ready.
