Bitcoin madness

I'm holding Bitcoin, and as told I should, I am in control of my private keys. However, for some reason I feel like I'm being robbed in some way. What if this scaling debate would have been resolved by all parties involved, with 1 united consensus. No fork. My Bitcoin would probably be worth more than bitcoin + bitcoin cash put together. And what about those that are able to sell bitcoin cash now. Where does that money come from to pay those that sell now. It cannot come from thin air. It must be coming from bitcoin. Who hatched this plan, to swipe off the top, the bitcoin I had paid for.
