I don't this this is an issue of no one wanting to lead. There are plenty of patriotic leaders out there. The issue comes down to this:
The conditions that brought about our first Civil War...or even our war for Independence (which in some ways was a Civil War itself - English subjects against English subjects) do not exist here...yet.
Today's America is increadibly decadent.
Anyone can go to their local grocery store (in many cases, a "super" market or mega store) and find all the food they could ever want or need. It's only a question of money that determines how much and of what you casually decide to purchase and (most likely) place in your modern vehicle equipped with air conditioner and a heater (just to name the basics).
You'll go home to a modern home where you most likely have all the running water (cold, warm or hot, your choice) and heating and air conditioning you'd want at your near instant disposal. Again, only money determining how much you consume.
Most will turn on a giant ultra thin television and tune in just about any kind of programming one could want. Personal preferences and household finances determining if you have 10, or 100, 250+ channels available.
If not the T.V., then a computer or "smart" phone, where one can get games/news/banking/information from anywhere in the world or do work with the press or slide of a button. Most will charge those modern electronic devices by plugging them into an abundant supply of electricity that is available anytime you want it 24x7 (save for short term power outages).
The list goes on and on. Today's America is far more decadent and individuals far more "wealthy" that our predecessors of the mid to late 17 or 1800's were for their times. As awful, unlawful and in many cases treasonous as the left has become ...there is no way people are putting all of our modern decadence aside to take on any form of significant marching (or taking up arms).
The time is not yet ripe, but that tipping point is approaching so long as Trump fight's mostly alone at the federal level. When will it happen? Certainly not days or months. But years? Decades? Time will tell.
