"bent out of shape over something you can't even remember"
I'm pretty sure he probably remembers he's been circumcised whenever he goes to the bathroom, takes a shower, changes his underwear...
If a person is drugged or blackout drunk is it ok to rape them if they don't remember?
Is it ok for a parent to put tattoos on their child if they get it done while the baby is young enough not to remember?
Someone can come to terms with a situation and still be allowed to be angry about it.
While I get your point, it didn't read as supportive to me. To me it read as a statement of "this is what I observed" not "this is my judgement of the kind of person he is."
Like if someone asked me what kind of person a coworker was. If my answer was "I saw them do their job" it can be a factual statement of my experience and really, isn't necessarily helpful. It just means I didn't witness them doing anything bad.
Edit - rereading as someone just posted a copy of the letter. While I can see some focus on positive interactions with his daughter, it still strikes me as a factual "this is what I observed" and far less the emotional supportive standpoint that bled through from some of the other letters that were submitted.
