I'm not the author I can't get exactly what his views were definitely when writing the book but if you read any of his other work, especially The Moon is a Harsh Mistress, you'll see that he's much more antigov/anticontrok than anything.

People who use this book to twist it is as support of fascism are prob fascist themselves. Doesn't make them right. I would absolutely advise you not to converse with anyone like that.
