My son was born in San Diego, California at Balboa Naval Hospital. His mother is a foreign citizen. My son is 100% American and in 34 years, 3 months, he'll be eligible to run for president of the United States.

Your son, while undoubtedly a citizen by birth, and thus a native born citizen is not a Natural Born citizen, which is a citizen ship status that requires the child to be born in the jurisdiction of the United States to two citizen parents.

There was a time when, perhaps, the father's citizenship alone would have been determinative, but that time has long passed if it ever existed.

I disagree that the time has passed. The Constitution and the eligibility requirement should be interpreted as written by the authors using the language the way it was used back then and not the way current society uses it or understands it to mean. You obviously understand the difference between Native and Natural. Stand firm.

Until the early 1920s, when a foreign national woman married a US Citizen man, the woman became a US citizen, automatically. Now, she doesn't, although it's easier for her to get citizenship, depending on particulars, than someone else coming here from here home country.
