I am looking for a word that describes general phrases that makes one feel good but has no real meaning, such as, "I'm for tolerance." Well, maybe in some things you are but in others you aren't (murder). This is just a "______."
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’
Perhaps rhetoric is the word your looking for. Or maybe 'mere rhetoric'.
b. Language that is elaborate, pretentious, insincere, or intellectually vacuous: His offers of compromise were mere rhetoric.
