“I would end the welfare state.”
That would definitely bring things to a head.
“Anybody who wants to start a war/riot/insurrection over it gets shot down dead in the street (or wherever) like the rabid dogs they are.”
It would be a blood shed on both sides. Another civil war with many whites on both sides. It would probably resemble more a left vs right war, an ideological war.
Perhaps secession should be given another chance.
Secession? Who and what secedes? I'm not sure what I would have been in 1860 (quite possibly a Confederate), but I'm pretty sure I'm a Unionist today.
