Core is not the same team of developers that it was back when satoshi was around.  You have to understand that in a permissions system, any and all implementations and forks can exist.  The debate that's really going on is whether they think BCH is viable as a currency and whether its developers are competent, but some people weirdly delude themselves into acting like only Core could ever be competent, and that seems like a dangerous mentality which you're on the brink of having.
You are incorrect.  In the long term, miners will just follow the economy.  If BCH is given a price of 0.25 BTC, then in theory it would end up with 1/4 of BTC's hashrate.

They wouldn't do it exactly, but just like how a lot of GPUs are being bought for altcoins, it's all about the pursuit of profit.
I agree.  I think that people let their opinions get in the way of their judgement.  Even if you don't like BCH at all, you have to recognise that it could easily have a lot of hype in the future with the right whales.
