Don't be too hard on yourself.
If it has taken you five years and a journey through eighteenth century Swiss philosophy to develop your choice/preference for a narrow "two citizen parents and born in the United States" definition for NBC, then you should expect that it may take you some time to shed the old choice/preference and to exchange that choice/preference for a somewhat broader "citizen at birth" definition for NBC. As Obama's eligibility becomes less relevant and Cruz's eligibility becomes more relevant, you may find that process to be inevitable.
Patience. ;-)

You might even pass it.
Don’t bother replying to me, I never read your comments, and didn’t read your reply to me.
Life is too short. Just letting you know.
