That doesn't justify the ridiculous claim that the nationalist movement wants only the independence of Luzon when the idea of a united Philippine archipelago is already solidified a few decades before them.
Yes, Bonifacio used the term Tagalog. But it was only an attempt to create a unique identity for a new nation. He's that idealistic.
It's his thing, unfortunately. It's also a disease of misplaced Filipino nationalism. The idea that there were large indigenous states that spanned the Philippine Archipelago, and that without Spain we would have developed as in OTL without any of the garbage of Spanish rule.
And there was a lot of that, but Spanish rule is also essential to the identity of the Filipino today, both positive and negative.
Bonifacio's Katagalugan is a successor of Saludang - Rizal does not want Philippines to be independent because the people of the Philippines don't know their history, Katagalugan is composed of all the Archipelago but institutionally and culturally it is based on Saludang/Kingdom of Tondo.
Three hundred years. We were scattered and pagan and isolated before them, we were united and Catholic and connected to the world after them.
