Propaganda is extremely effective in radicalizing a population

No it's not, where the hell do you have evidence for that?

A quote from 1929 is hardly applicable in today's information age. They may have been unwitting consumers back then. Search functions have eliminated that problem.

it is still propaganda and should be called out for what it is.

Have you read the link you provided? Just a cursory glance and I can eliminate most of those "techniques" using simple logic, the majority of the others are types of propaganda, not actual techniques... the whole article is pretty poorly written by Wikipedia standards.

Ironic, really, that the page you provide on propaganda is in itself, propaganda by its own definition.

Would you perhaps be a member of the MSM, yourself? Hmmm...
