You are incorrect. Let's take away by "no one ever" for a second. You would struggle greatly against anyone with any level of aptitude for research if you tried to take the position you're taking in arguing that the bombastic approach is more effective historically. You guys conflate being assertive with being a douchebag and that's the point you guys keep missing. I go hard at people's heads at times because certain situations call for it, but it never involves calling them an idiot. The only way the stance you're taking can many any sort of sense or have any sort of current or historical bearing is if you assume what I'm saying is akin to the CNN habit of pretending everyone is making an equally reasonable point or that we should let people make arguments unabated.
If we really sat down, tossed out our collective anecdotes (and I've got more than most people) and did a historical analysis and a positive analysis, the weight of history and the present are both greatly on my side in educated societies. The only thing more effective is brutally imposing your belief upon others. As someone who watches government and how messages have to be communicated and how coalitions are built you know this.
