Re: business: Not being moral there either. If you have never run a business, it's possible to remain in the cozy state of theoretical rather than practical political philosophy and action. Capitalism especially at the large corporate level is extremely corrupt but not because capitalism is inherently corrupt. When government is this big, business must be in bed with it if it is to survive.
You can criticize Trump for many of his political buy offs, however in Trump's business, you pay off everybody. That is a function of big, corrupt government.
That is why Trump can in the same sentence say how many people he's donated to, paid off, bought, and simultaneously despise it / them. They are whores, but they force you to have sex with them and pay them at gunpoint.
'Sin' originally means 'to miss the mark', so to use it here only means 'he's done things we can be legitimately concerned about or of which we should take note, keep an eye on' ... but in context, and you might not have that context if you have never been at the mercy of a politician to merely by something or get a permit that should be freely available in a non-collective regime, you must do what Trump did to survive.
So, I'm merely putting things in context.
Trump knows about the deeply rooted corruption and rot in government and how they are shakedown artists and as you said, anyone in business has to play the game or get out of business. He didn’t like it but there was no other way. He wants to change it.
Gen. Patton had very rough edges, used foul language and was no saint but he was a good general. We need the equivalent and clearly Trump is the equivalent. We need a pres with REAL LIFE experience in the fields Trump has, and no other candidate has any at all.
