He's trying to be clever and say "civil war" without saying "civil war". The LARPers on the right seem to be enjoying this a great deal. I'm sure the FBI will be very interested in their calls for violence.
Your assertion that Twitter has somehow "deplatformed" half of the electorate, despite even a cursory look at the site showing a vast amount of Republican and pro-Trump content, and the fact that far less than half the country even voted for Trump to begin with, is ridiculous, and it's obvious from your comment history that you're a troll account anyway.
But yes, Parler, Gab, Voat and other alternative platforms were created by right-wingers specifically to have a "safe space" where they could post freely without having their views confronted. They were not deplatformed to those sites, they left for those sites willingly.
Good day AnonDataSci.
If Twitter would act honorably and allow open conversation, conversations that obviously don't contain death threats, etc, then there would be no need or even desire for an alternate platform.
Everyone should be on Twitter, saying whatever non-illegal political content they want, but they can't because Twitter is disobeying the law.
