There is no room for a truce. To oversimplify it, liberal democracy was basically a 200 year armistice between liberals and conservatives. Now, both sides see the imminent prospect of either final defeat or final victory. The only thing that matters is winning. On this, both sides are right.
What does winning mean for either side? The other side doesn't just cease to exist. Nor do the people in the middle our outside the dichotomy. Does it mean autocracy? And how will the prevent revolution? How does it prevent an ongoing, unwinnable civil war which fizzes out to another armistice after everyone is sick of not winning?
Consider that in 2008, a majority of the country opposed gay marriage, but in 2022, a majority support and it is considered completely unacceptable to advocate for a return to the old order. That's what victory looks like. Consider too that in 1990, a majority of the country was still against interracial marriage. Today, those same people would probably deny they ever felt that way, maybe even convincing themselves of that lie. That's what winning looks like.
Today, a biological male can win women's sports competitions and a five year old can be recognized as transsexual. A robust majority of the country opposes it, but everyone outside of Republican electoral politics[1] is scared to put their face to any opposition to it. This is starting to look like final victory.
