There's multiple takes on what the protests are. Some say peaceful, some say they're riots.
If they continue for much longer, and keep going with messaging Trump needs to be prevented from becoming next POTUS, then may as well declare civil war. While Clinton did win majority of popular vote, you'd essentially be telling 60 million other people, sorry we are taking this from you. Deal with it. And given the precedent, riots and all, along with the idea that there are some Trump supporters who are violent, anti-whatever, you think they'll sit by idly? You really think that?
The current reality is a) Trump stays as next POTUS (like pretty much every other election in American history, b) Pence takes over, c) Dems take over executive branch and still Pubs rule every other level of national politics, though SCOTUS would probably go the other way. C is currently the end game as far as I think some protesters are concerned. Those that think C will occur through only peaceful measures are entirely delusional. Those that think you can keep going on with protests without end, are plausibly delusional, but depends if they truly can maintain absolute non-violence of all protesters. I highly doubt they can.

You tell me it's the institution
