There IS one left-handed big advantage to carrying a gun: if you have
an IQ over 80, it will make you expert at avoiding any possible
confrontations

That is exactly true.
The Florida CCW course is basically just telling you that if you shoot someone
you will probably go to jail, even if you do eventually get released, thousands
of lawyer dollars later. I will certainly have eaten a lot of **** before I
finally decide this is a life threatening situation worthy of deadly force.
I found out years ago, carrying a gun makes me a very meek and mild individual.
That is why I usually leave it home ;-)
