These people never stops about the fact that bitcoin cash is just another alt coin in the market. Bitcoin is bitcoin and it will never be replaced by another alt coin, it can be upgraded into v2.0 or something similar but it will remain bitcoin. Put that in your mind that everyone will still stay on the original bitcoin. And that's not BCH.
But you're forgetting that Core just forced thru the Segwit changes to "original Bitcoin". So "original Bitcoin" is not really Bitcoin anymore either. Rumor has it "original Bitcoin" may forking again when they refuse the 2MB hard fork of Segwit2x, because Core wants to start banning Segwit2x nodes...
At some point "original Bitcoin" could be so crippled that it loses value, That's where Bitcoin Cash could step in.
Bitcoin will always remain bitcoin. Because of Segwit it will not be called as the original bitcoin anymore? If you say so, if you want to push bitcoin cash for another highlight or you can see that this is going to be a good choice for everybody when it comes to transaction. Do it for yourself, well it's a fact that bitcoin's value can lose suddenly but if you think that BCH is the successor, I don't think so.
Forget about the scaling war for a minute. And don't worry about names.
What you seem to be oblivious to is that "Original bitcoin" just forcefully soft-forked to a completely different block storage and validation system (Segwit), which is as of yet unproven. Miners who don't wish to use Segwit have NO CHOICE but to use it if they want their blocks to be accepted. So "original bitcoin" has changed by 6000 lines of code, and the network is working very differently at this very moment. Most people on this forum seem happy about this new change, but that doesn't mean that "original bitcoin" remains the same. Furthermore, new attack vectors have been uncovered by Segwit.
Bitcoin Cash, on the other hand, opted to remain with the ORIGINAL BITCOIN block storage and validation method - no Segwit. Are you starting to see my point?
