OP, the followers of Bitcoin Cash can say anything they want, but be careful with their subjective opinions. Some of them are designed to confuse, manipulate and to take you away from the facts.
At any rate, all I know is the word "Bitcoin" refers to what "they" call "Bitcoin Core" for most people except for Roger Ver and his followers.
If Roger Ver started a Bitcoin giveaway, be careful. It might not be really Bitcoin. Hahaha.
Agree with you. The way they are trying to lead the BCH campaign didn't give desired results. All in all, for the most of people there is only one Bitcoin, as you said and I don't see any reasons to change this opinion.
