The opposite of "more unsectarian" are words like sectarian, bigoted, narrow-minded and intolerant. Being unsectarian means being open-minded, not discriminating based on religion or ideology, and showing respect and tolerance towards people of different beliefs. Conversely, being sectarian is characterized by a strong attachment to one's own beliefs or religion, often leading to a biased and judgmental attitude towards others. Bigoted and narrow-minded individuals also display a similar lack of open-mindedness and respect towards others, often refusing to consider or acknowledge opinions that are different from their own. Therefore, it is important to strive for an unsectarian and inclusive attitude, as it promotes understanding, acceptance, and respect between individuals and communities.
