What people don't seem to get is that there is much worse things than civil war (as horrific as it may be).
Now there won't a civil war in the US, mostly because right wingers are absolutely exceptional, everytime they say 'if the left starts a civil war they'll be curbstomped'. OK that's probably true at this moment in time, but why in the fuck would the left start a war when they have been winning for almost sixty years.
There may be some exceptional useful idiots that are absolutely crushed about Trump, and then I think most of them are just pretending because they think that their faux outrage will help stop Trump somehow even if it's a little, and they're probably right since a lot of people fall for the drama. But still, the truth is that Trump is barely a small inconvenience in the grand scheme of things.
Overall their agenda keeps advancing and they keep getting in control of every important and semi-important institution in the US, eventually they'll get the US military too and eventually they'll also repeal the 2A (and probably the 1A) at least in practice in most states and it's then that they may start a tiny civil war against the few remaining to bring them to heel.
The left is fighting a long ass war and the right (with some exceptions) is completely oblivious to it.
