Noun
bloviation (countable and uncountable, plural bloviations)
(US, possibly originally Ohio, informal) A boastful or pompous manner of speaking or writing; a lengthy discourse delivered in that manner. [from mid 19th c.]
The perpetrators of the actual bad stuff that does real and lasting harm to people, like leakage of industrial chemicals into water systems, seem to get not so much as a second glance; the bloviation from media pundits and think tanks creates false problems that waste time and energy debunking.
