The appearance of K.Trudeau on infomercials is sensationalism to you. What evidence do you list to back this statement up. I didn't see any. Why don't you amuse and surprize the readers here with some?
According to what you posted, you feel that people who watch the infomercial on TV, then buy the $30 book, then go to a website similar to CureZone to read the details on how to carry out the (body) cleansings Trudeau talks about, to learn what result(s) to expect, is vulgar to you.
What if a lot of people don't agree with you? They may believe that knowledge comes from experience rather than name calling, a characteristic you have if you read back through your posts.
I have listed definitions of sensationalism so you will know how to back up the claims you make in a more empirical way the next time you use the word. What do you accept as evidence (for it)?
