All talk is aimed at impacting how people think and perceive the world around them. So, basically, every word I have ever said was an attempt to brainwash. Every person is ideological, even if they don't fit into the neat little categories of republican or democrat. Therefore, every word we say is ideological. Therefore, every word we say is propaganda. The words "brainwash" and "propaganda", as you've defined them, just add a negative connotation to something we all do.
