> The idea that "left means more government" is also very ahistorical and feels uniquely like a product of modern American political discourse. The origin of the left-right distinction is literally the abolition of feudalism, i.e. replacing a fixed hierarchy by birthright with egalitarian democratic elections. By 1776 standards the founding fathers were left-wing radicals. The right would have literally defended the Crown.

Look at how many Black Americans supported the Loyalist side. Many of the American Founding Fathers were slave owners and supported the continuation of slavery. The British Empire promised freedom to American slaves who supported the Empire, and it mostly delivered on that promise. Both sides were very racist, if judged by contemporary standards, but I think there is a decent argument to be made that the racism of the British was on the whole a lot milder than that of the Americans.

The British Empire, including what is now Canada, officially abolished slavery in 1833; the United States would not finally abolish it for another 30+ years. (And it took a bloody civil war for America to do it; the Empire’s abolition of slavery was largely peaceful.) But in actual fact, slavery was de facto rendered legally unenforceable in most of (what is now) Canada by a series of court decisions in the 1790s, so in practice slavery was abolished in Canada over 60 years prior to its abolition in the US.

While there was widespread social discrimination against Black people in 19th and 20th century Canada, it was generally much milder than in much of the United States. The British and Canadian legal systems generally accepted the theoretical legal equality of all citizens regardless of race, even though it often failed to enforce that theoretical equality in practice; by contrast, the legal systems of many American states contained explicit discrimination against Black citizens.

Lynching was a great scourge on American history, of which Black people were the disproportionate (but not exclusive) victims. Many Americans defended lynching as a form of democracy. Judges, law enforcement and prosecutors in the US were very sensitive to public opinion – in part due to their widespread direct election – and were often loathe to properly investigate, prosecute and convict lynching cases if public opinion appeared to approve of the act. Likewise, many American jurors believed that it was appropriate for them to defer to public opinion in deciding cases, and return "not guilty" verdicts in popularly approved lynchings even when the evidence clearly pointed to guilt.

By contrast, the British Empire strongly objected to people taking the law into their own hands, and would-be lynchers in Canada faced far greater odds of successful prosecution for murder (and its then near-mandatory death penalty) than in the US. British culture–including among politicians, law enforcement, prosecutors, judges and jurors–prioritised upholding the rule of law over popular opinion to a much greater extent than American culture did. Due to this cultural difference, lynching was extremely rare in Canadian history – a mere handful of isolated incidents, compared to many thousands in the US.

So, who were the "egalitarians" and "left-wing radicals" in the American Revolution? I think we should seriously consider the possibility that the American Revolution was in fact a reactionary right-wing movement, widely supported by slave owners who lived in fear that the British Empire might forcibly liberate their slaves, and not really a "left-wing" one.
