I've noticed that abstract and vagueness is used to tell half truths all the time.
Half-truth - Noun - A statement, especially one intended to deceive, that omits some of the facts necessary for a full description or account.
Socialists, communists, tyrants: they all use deception to gain power. They lump in the apathetic and the desperate with the extremists to create a following and thus power. Phrases such as 'all of us,' 'people,' 'they,' or 'we,' are all used to vaguely describe a group. The phrases put people that do not necessarily agree with the speaker together and influences the audience. The audience then feels they need to follow the counsel of the speaker. Using vaguely worded and unmeasurable words with only a part of the truth is deception; plain and simple, it is lying and wrong.
