...my son will have ... one parent who is a communist, more or less.
Lucky little chap! Actually I would say that my parents were 'different' politically, though they voted the same: one was a very bright autodidact who had terrible instincts, who voted Republican from a kind of Goldwatery viewpoint, and the other a person who despite existing in almost perfect ignorance understood politics and voted for 'better reasons' (in the sense that her reasons were more reflective of reality) from purely instinctive motivations.
It worked this way - one could think but was completely deluded, and voted for X for well-thought-out reasons which had no real application to X, while
The other could not understand
any intellectual argument, and voted for the same party out of vicious deeply held hatreds, fears, prejudices, and bigotry.
Now, the interesting question is - is this a false dichotomy?
