In such cases, the phrase "not oppose" can be a useful way to express a position without committing fully to it. However, there are countless other ways to convey such a sentiment, depending on the context and tone of the discussion. Some possible synonyms for "not oppose" might include "not necessarily disagree," "not actively opposing," "not opposed to considering," "not fully in favor of," "not completely opposed," or "with some reservations." These phrases can offer nuance and clarity to a conversation, allowing for more meaningful and productive exchanges.
