Wikipedia has a much more accurate definition, that differentiates between merely spreading information and doing so dishonestly and with an agenda:

Propaganda is information that is not impartial and used primarily to influence an audience and further an agenda, often by presenting facts selectively (perhaps lying by omission) to encourage a particular synthesis, or using loaded messages to produce an emotional rather than a rational response to the information presented.

For some highly mysterious reason, you didn't want to go with that. Oh, and it seems your claim that "the other definitions" say the same thing is obviously false, what with the most widely used source for definitions saying something different and all.

You say that right before posting a bunch of propaganda

By now it's obvious you're being intellectually dishonest, so you might want to take that claim back.
