Disregarding how you both feel about it, waving a nazi flag legitimizes and strengthens an inherently violent ideology of ethnic cleansing.
Intent - real or pretend - doesn't matter.
You DO know that the Nazi party of Germany was democratically elected right? It did plenty of good for plenty of innocent people who simply lived in Germany at the time.
Also, you know, by your logic almost ANY flag shouldn't be waved. All countries have been to horrible wars and killed aplenty.
Here, you are outside my argument, and from that perspective I have trouble disagreeing with you.
But inside the argument, I am correct (or "technically correct" from your perspective), and you are wrong - meaning, the Supreme Court, the American view consistent with the 1st amendment - that is more in alignment with my argument.
But I feel like I remember there being a set of academic terms that refer to each of our perspectives. Being inside vs outside the argument. Does anyone know?
And there's also the (very American) question of when "technically correct" is no longer correct anyway, like when being lawful is unjust, and civil disobedience is called for - oftentimes accepted by history (MLK's civil disobedience, boycotts, shutting down roads, etc) - a good example from this week is the perspective of the protesters who tore down that statue, and the perspective of the very long line of people who are seeking to turn themselves in to (falsely) confess.
For that matter, is Communism? Marxist-Leninist governments don't have a great track record, but there are plenty of individual pacifist hippie commies; the ideology of common ownership of production is not inherently violent and racist like Nazism and the Klan are.
You might want to check your Russian History, particularly Stalin's era, to examine the violence inherent to the ideology of common ownership, when applied Soviet style. Scholars debate on whether he killed 8 million or 60 million...

It eventually got taken down for good after increasing numbers of students from eastern Europe came to the college and pointed out that, to them, it was just as oppressive a symbol as the swastika.
Really this all should have got sorted out around the time of the Spanish Civil War; actual capital-C Communism is too tied up in Stalinism to be trusted any more.
Of course, plenty of people are happy to label their enemies as "communist" for supporting basic reasonable non-Stalinist things like universal healthcare. So the fact that someone is labelled a communist by their enemies, especially in America, means almost nothing.
