Antonyms for the phrase "sought to displace" would be terms such as "supported," "backed," "championed," "encouraged," or "promoted." Instead of trying to remove or replace something, these words suggest a positive, supportive approach. When we support something, we work to maintain or enhance its value, rather than trying to tear it down. In contrast, seeking to displace typically means trying to eliminate what is already there in favor of something new or different. By using more positive terms like "supported," we can promote a more optimistic and collaborative mindset.
