Let's be clear, Kirk ALWAYS knew about David. The dialogue in TWOK backs this up. He says 'how could you have never told him?' He knew. David didn't but Kirk did.
So all of you complaining about SNW breaking canon here, it's not. It's really not. Kirk knew and wasn't involved. He didn't care enough to be involved. Yes, I know the movie frames it as honoring Carol's wishes but that is such a lame excuse. Kirk's a deadbeat dad and he always was. He might feel bad about it, but he chose going to a conference over spending time with his son. Deadbeat.
And why is everyone so obsessed with Tarsus IV? I could write essays about how little I give a shit about that. Mostly because it keeps popping up in fics and I'm just so tired of it. Maybe I just don't like 'poor Kirk stories' but Tarsus was mentioned in one episode a million years ago and canon has never brought it up again. I don't care.
