Its so crazy to me that some Americans label abstract ideas as evil. Communism == evil. Socialism == evil. Many welfare programs == evil. Immigrant labor == evil. High minimum wage == evil. Some languages, religions, cultures == evil. Stop subverting the English language because you're too lazy to check a thesaurus. None of those things are evil.
They are, rather, making a statement about strategy and messaging in American politics; a point which has borne out in countless political contests over the past decade alone. There is a reason why Republicans try to say "socialis(t/ism)" as often as possible. It works.
One example off the top of my head is Florida during the most recent presidential election. The Republicans beat the drums of socialism broadly and especially targeted at Cuban-Americans who immediately think of Castro. Voters who might otherwise skew towards Biden went Trump.
Again, that's one example, but the point is about _messaging_ and how the electorate in America broadly (not 100%, everywhere, etc.) responds to "socialism". (Nationalization being, of course, clearly tied to socialism.)
Perhaps you should rephrase this as "calls for nationalization run counter to my own free-market ideology" rather than a) assuming you know what everybody else thinks, and b) suggesting that conventional wisdom should dictate the bounds of acceptable discourse.
Not to mention, plenty of countries — the US included — have successfully nationalized companies and entire industries.
