The ambiguity is not there for me, to me the extra comma adds a different aspect to it. The first sentence is fine as I can see and recognise that it's a list, in that the writer's parents, Ayn Rand and God are 3 parts of that list. The comma makes me read it in a different way so the second comma I read as a list of 2, the writer's parents (who's apparent name is Ayn Rand) and God. This is the way I was taught. Out of that wikipedia example also, I wouldn't put a comma in front of the 'because' like that example has in the sentence after parentage. I don't understand the need for it. |
Ah but understand, many people may see it the exact opposite as you do. Though, generally, I do agree with you on this.
As for the second part of your post, the comma is before 'because' and after 'parents' as a result of it being a clause inserted into the sentence. The sentence would read perfectly without 'because Ayn Rand and God can be read as in apposition to my parents.' The clause was an unnecessary, but useful, addition to the sentence.
