Agree with the reasoning. Are you buying more bitcoin? DO you think you should sell bitcoin cash or keep it in a wallet and see if it gains adoption. I think the split almost makes bitcoin cash more powerful because if lightning networks do not work as well on segwit then bitcoin cash could be reverted to the main coin since it didn't adopt segwit.
I still wish there was only one bitcoin and less confusion. However, if the white paper said this was a power in its currency then who am I to disagree. I'm a Realtor not a cryptographer. :)
