Why did rizal wrote One who does not treasure his own language is worse than a beast and putrid fish?

Rizal wrote this statement to emphasize the importance of national pride and identity. He believed that language was a crucial aspect of preserving one's culture, history, and heritage. By not valuing one's own language, Rizal saw it as a betrayal of one's own roots and a denial of one's identity, likening it to being worse than a beast or putrid fish.
