Are you being disingenuous there or cynical or both? Any reader can see what I wrote..... The show being about a rampant pro-Castro communist. Then as it seems, Oswald became a humble mealy stock boy at a book supply like nothing ever happened.
Your "humbly mealy stock boy" was telling people (the Paines for example) that he was a Marxist and that he detested the American political and economic systems.
In fact, according to Michael Paine and (others who were there) he attended an ACLU meeting where he stood up and warned about the far right in Dallas (Walker specifically) and got into a disagreement - reportedly a near fight - with another member over their disagreements. He said he didn't like the ACLU because it wasn't "political" enough.
Sure he was quiet on the job because he didn't want to get fired - again - for expressing his anti-US views.
But he was still agitating for Castro and for his Marxist beliefs. Correction: Not true on that last point about Castro. But he was still describing himself as a Marxist to others.
