Iraq dominated the headlines throughout the fall of 2002 and into the winter of 2003. Public opinion on the wisdom of war, however, stabilized relatively early and slightly in favor of war. Gallup found that from August 2002 through early March 2003 the share of Americans favoring war hovered in a relatively narrow range between a low of 52 percent and a high of 59 percent. By contrast, the share of the public opposed to war fluctuated between 35 percent and 43 percent.
Looks like Americans are even more happy with murdering people if its done by a puppet.

Most Americans own some means of accessing the news (be it television, electronic devices, social media). Even if you don’t regularly sit down to watch the latest MSM talking shithead, just one impression of events (as well as second hand impression via word of mouth) can be enough. Bear in mind that social ostracism is also always an implicit concern for breaking with the perceived “consensus”.
This is why those rallies happening now are so important (regardless of what I think of IfNotNow) and why MSM is tripping over themselves only selectively reporting it.
