Opposites of "protesting" include terms like approving, endorsing, and supporting. While protesting involves standing against a particular issue or action, supporting is to stand with it, agree with it, and back it up. Endorsing is similar to supporting but with a hint of promotion - endorsing a product, person or action means advertising it to a certain extent. Approving is often used to express one's positive opinion about something, whereas protesting represents the opposite side of the situation - a negative opinion. While protesting can have its own value, the antonyms of protesting show ways to express different opinions on issues.
