One story:
From a son's perspective, Chris Wallace talks about his reaction to finding out:
What sweet solace I took in blaming my father for all of my perceived failings in masculinity. No wonder I was so different from the back-slapping, arm-wrestling boys I grew up with. Lacking his introduction into their codes and secret handshakes, I had been forever closed off from their fraternity. … "I feel like everyone’s been laughing at me my entire life," I moaned. My mother turned on me and said quietly, “It wasn’t you they were laughing at.” My pity party ended then and there.
The truth was that even as I wanted to harbor a Shakespearean grudge against my father, I was warmed by his accidental revelation. I thought about how he had grown up very alone, in a conservative family during the conservative fifties. How he had no one he could speak frankly to until he met my mother working on the original production of Hair.
