The antonym of the word "more admitted" can be "less accepted". When something is less accepted, it means that it is not as widely agreed upon or acknowledged as something that is more admitted. The concept of acceptance and admission is often used in the context of opinions, facts, or experiences, where some may be widely accepted and admitted by a majority, while a minority may not agree with it. By using the antonym "less accepted", one can express how a view or a statement may not be as popular, agreed upon or admitted as something that is more acknowledged or accepted.
