That's only half right.
A civil war is a war between citizens of the same country who are fighting for control of the government of that country.
That's not what happened in the US. The South just wanted out of the union to go their own way (because of Lincoln's taxation policies that were going to crush the south)...like one party to a marriage wanting a divorce.
The North wanted no part of it and started the thumping.
(More nonsense that we've been fed all our lives is that it was a war about slavery...but again, it was no such thing, nor was Lincoln any shining hero fighting for the abolition of slavery).
The point, as with many other things in life, is that most of us have been conditioned to believe certain things to be true...in this case, that certain historical events occurred/unfolded in a certain fashion leaving lasting impressions on us, for better or worse, often positively reinforcing or otherwise affecting our personal value systems with respect to what we believe to be right vs wrong. Meanwhile we are the victims of believing a false narrative that we have been fed and we have unknowingly used that false narrative to affect our view of the world.
The net effect is millions of people walking around believing that many "important" events and the lessons learned from them are part of the cosmic firmament when it just ain't so.
Let that sink in for a minute.
