look at lauda.. lol
1. BU does not cause bilateral fork. LEARN CONSENSUS
2. core want a bilateral split. they are begging for BU to split, but then pretend its "harming the network" if BU did split (hypocrits)
3. core want the split but want to play the victim card
4. BU, XT, classic, bitcoinj and the others DO NOT want a bilateral split. and if you READ THE CODE you will see its USING CONSENSUS to keep things together as one network
5. to create a bilateral fork nodes have to INTENTIONALLY BAN communications from each other to prevent orphans (bitcoins natural and USEFUL safety mechanism)
What you are describing is what I and others call a bilateral hardfork-- where both sides reject the other.
I tried to convince the authors of BIP101 to make their proposal bilateral ... Sadly, the proposals authors were aggressively against this.
The ethereum hardfork was bilateral, probably the only thing they did right--
lauda please please please.
wake up. have some coffee then use the energy you have to suck up to gmaxwell, and use it to LEARN CONSENSUS
