"Seek to displace" means to replace, remove or supplant something else. Its antonyms are words that have the opposite meaning, such as "support," "maintain," "preserve" or "uphold." If you seek to preserve something, it means you want to keep it and prevent it from being replaced or removed. If you want to support something, you are giving it your full backing or approval. Maintaining something means upholding its current status or condition, while upholding something means carrying out its principles, law, or tradition. These words are used to demonstrate the opposite of seeking to displace. So, when using these words, the intention is always to protect, maintain or improve the status quo, rather than replace or remove it.
