Yet when you let them talk, and stick to the facts, they will start making fools of themselves sooner rather than later.
It's a mistake to assume that a majority of people can even be reached through argument, reason, facts, pie charts, etc. Most folks just don't care or refuse to even notice until it's dropped right in their laps. Like the old saying "we wait until a rainy day to fix the hole in the roof."

That's a pretty good article illustrating the phenomenon. An east-coast urbanite, educated and liberal, hates Trump and his proposed wall but travels to the Southwest and talks to actual people being impacted directly by illegal immigration and is surprised by what he hears. Even the majority of Hispanics down there hate illegals and want a wall!
It's just a sad reality of humans. We can talk and talk and show them Youtube videos and bar graphs and try to explain to them how the dominoes are inevitably going to fall and, sadly, a majority just won't accept the reality of it.
