A friend is looking for a translation of his album title to English. The title in Persian roughly means "slogan wishes" if split apart and translated word by word. The actual meaning is "wishes that everybody chants like a slogan but most neither work towards nor achieve." What would you call it in English?
Consider calling them platitudes.
platitude noun A remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful. ‘she began uttering liberal platitudes’ - ODO
A platitude is a trite, meaningless, or prosaic statement, generally directed at quelling social, emotional, or cognitive unease. Platitudes are geared towards presenting a shallow, unifying wisdom over a difficult topic. However, they are too general and overused to be anything more than undirected statements with ultimately little meaningful contribution towards a solution. - wikipedia
an avowal of advocacy, adherence, or allegiance expressed in words but not backed by deeds —usually used with pay
Similarly from AHD:
Verbal expression of agreement or allegiance, unsupported by real conviction or action; hypocritical respect.
Lip service continues to be paid to resolving regional conflicts, but there is no sense of urgency (Henry A. Kissinger).
And most pithily from Vocabulary.com:
an expression of agreement that is not supported by real conviction
Some relevant synonyms given by Thesaurus.com include:
- empty talk
- hollow words
- smooth talk
- sweet talk
- token agreement / tokenism¹
¹ In the only making a symbolic effort sense, not in the sense specific to affirmative-action or similar law.
While the previous answers are quite good, I would also suggest you consider pipe dreams:
an illusory or fantastic plan, hope, or story
Example: His plan for starting his own business was just a pipe dream.
Synonyms: conceit, daydream, delusion, illusion, fantasy
Related words: mirage, concoction, fable, fabrication, fiction, invention
Definition of pipe dream for English Language Learners: a hope, wish, or dream that is impossible to achieve or not practical
This word carries a lot of specific connotations that your friend probably don't want for his/her album, but the (quite new) idea of slacktivism could be fairly well described that way.
