A more thorough explanation:

Definition: Something that is objectionable is open to opposition, especially when there is a reason or argument against it. It can also be called exceptionable.

• The movie's violent scenes were objectionable to some viewers.
• Her behavior at the party was objectionable and caused many people to feel uncomfortable.
• The proposed law was deemed objectionable by many citizens who felt it violated their rights.

These examples illustrate how something can be considered objectionable when it goes against what is considered acceptable or appropriate. In each case, there is a reason or argument against the thing that is objectionable, whether it be violent scenes in a movie, inappropriate behavior at a party, or a law that violates citizens' rights.
