The divisiveness is because we will not surrender to Trump's values. It's better to tear the country asunder than to surrender to a set of values that are completely destructive to everyone who's not a rich white CIS hetero male. Because the alternative is no end of suffering to everyone who is not a rich white CIS hetero male.
This appears to be founded in the mistaken belief that there politicians that put anyone but themselves first, i.e. the left and the progressives. Fundamentally both seem to agree that life is better for all (not true, only their favored groups) when the people's decisions for themselves and their lives are dictated for them and enforced at the end of the barrel of the government's gun.
The free market provides the most at the least cost, due to it's continued competition. Remove competition by installing regulations, all enforced at the end of the barrel of the government's gun, the result is clear, supply shortages, and poorer service at increased costs. Such are the examples through history, one's that I'd rather not repeat, as once the government has control of something, the government bureaucracy isn't likely to give it's control over it. Best not to have that government control if not needed in the first place, and even if in dire need, extremely limited.
Ultimately it comes down to not backing down on our values. We're not going to let Conservatives take us back 60 years, culturally. If the Right keeps stealing elections with voter suppression then the nuclear option is rebellion. You're seeing that rebellion in action, and considering that the majority voted against Trump, it's a war you can't win.
There's no "Conservatives take us back 60 years, culturally" going on, at least not hat I can see. What's your unfounded fear?
And apparently your memory is very weak because "make the country ungovernable" was the CHIEF strategy of the GOP.
Sorry, but no. It's the left and their fermentation of riots, such as we see in Brekley and another locales, all of which is echoed the increased violent rhetoric about 'blow up the White House' 'Assassinate Trump', etc. etc. too many to list them all.
Saw none of that previously, until the left trotted it out, endorsed and supports it.
Sure, there's passionate political rhetoric. Just as surely as there's going over the line. There's a difference there, if you care to notice.
Swap the political positions, do you still support that same behavior? I rather doubt it.
If in reference to the Congressional GOP's legal behavior in congress from '08 on, it's called opposition party for a reason, which is much different. Comparing that to the violence and violent, vitriolic rhetoric now espoused as 'the new normal' by the left is an utterly false comparison, if you ask me.
Where in your false comparison where there riots in the streets, destruction of private and public property, physical attacks with weapons resulting in physical injuries on others whom have a different opinion, all of which we've seen as as of late by the violent leftist protestors / rioters?
