Antagonization, meaning the act of provoking or causing hostility, can have plenty of antonyms depending on the context. For example, in a diplomatic setting, cooperation, collaboration, or even conciliation could be antonyms of antagonization. In a relationship, kindness, empathy, or understanding might be appropriate opposites. Meanwhile, in a competitive or confrontational context, the antonyms could include negotiation, compromise, or even surrender. Additionally, in a more peaceful and harmonious context, the opposite of antagonization could take on even broader definitions such as love, harmony, or unity. Ultimately, the antonym of antagonization will depend on the specific circumstances and goals at play.
