There are two seperate issues right now. The blocksizelimit issue, and the Bitcoin-XT issue.

IMO the blocksizelimit should be raised or removed altogether. It has been raised before twice and both times not many people cared. However what I am TOTALLY against is Bitcoin-XT.

How Bitcoin-Xt works is this:

Right now its the same as Bitcoin. It connects to Bitcoin Core nodes, you can import your wallet into it and you can spend your coins at merchants that use XT or Bitcoin Core. The main difference however is that miners running XT add a message to the block they mine indicating they are running XT.

Once 75% of the hashpower is running XT, the bitcoin-XT nodes will stop connecting to Bitcoin Core nodes and they will now be on a separate network/currency. The bitcoin core network will still function with 25% hashpower and will still work as normal. What happens next nobody really knows, but if XT triggers then there will most likely be two different Bitcoin currencies for a period of time. The XT developers hope that most people will then switch to XT or will have already done so by this point.

Note that it is NOT nodes, users or miners who get to participate in this vote. Only mining pools do and the XT devs claim they have the chinese miners on board. Running a node is not voting, nobody gets to vote except for the OWNERS of the mining pools, less than 10 people.

I am totally against changing Bitcoin in this way. It is highly risky and not fair even in the slightest, we could very easily end up with half of Bitcoin users running Bitcoin Core and half running XT. This way of changing Bitcoin is too dangerous and that is what I am totally against XT. We need to change Bitcoin Core like we did before and raise the blocksizelimit. If people are stalling the process, we need to try and fix it the right way and not try and change bitcoin some other way, even if it seems hopeless, it's still a better shot than changing it this way when 2 out of 3 Bitcoin expose oppose the change.
