Because, like a spoiled child, they have learned if they keep on screaming someone gives in.
And now the screaming children are in the tree house (or basement) planning to create so much civil unrest on Inauguration day that he may have to call out national guard just to protect the (stampeding) public from themselves and then the screaming children will claim footage of law enforcement attempts to stop property damage and assault were actually just the “fascist’s first day in office” and a portend of his ultimate goal of putting all lefties behind hot-wired fences in some unused land in Wyoming. I know Wyomies did nothing to deserve that.
That footage will be passed down for generations of leftie indoctrination - the “narrative” will say that lefties flooded public areas just to watch the inauguration when suddenly they were attacked by trump’s shock troops....
Nailed it.
Real adults never give in to screaming children.
The democrats also control access to insider parties and celebrations. If the winning republicans want to be invited, and more important if they want their wives to be invited, then they have to "compromise" and show "bipartisan good sportsmanship". Sadly, most republicans obey, especially McCain, Romney, Graham, and the rest of the RINOs.
If two military units go to battle, the losers do not tell the winners how they want to be treated.
There is a good example where the losers repeatedly try to dictate the terms of their loss and see it as a victory - the PLOstinians.
They have lost every war since 1917 and yet, today, the losers and their sympathizers are trying to tell Israel what to do and how to capitulate.
Once in a while my kids would think that a tantrum might work, usually because they saw it work for some other kid in the grocery store. It never worked. Never. What they learned was that Dad was in charge and he loved them very much.
