What is intolerance primarily based on?

Intolerance is primarily based on ignorance. This concept revolves around a lack of understanding or knowledge about different cultures, ideas, or perspectives. When individuals are not exposed to diverse viewpoints or are misinformed about them, they may develop rigid attitudes and a resistance to accepting anything outside of their own beliefs. Ignorance fosters stereotypes, prejudices, and misconceptions, which can lead to discriminatory behaviors and a refusal to engage with others who may differ in their beliefs or practices.

Education and experience can significantly reduce ignorance by broadening one's understanding and acceptance of different ideas, thus promoting tolerance. In contrast, confidence does not inherently relate to a person's ability to accept diversity; it simply reflects how sure an individual is about their own beliefs. Therefore, ignorance serves as the foundation for intolerance, making it the most accurate answer to the question.
