Non-PRO Japanese to English Art/Literary Cinema, Film, TV, Drama

Dear ProZ members,

I'm uncertain of how to interpret 基本的に in the following dialogue. A boy is sketching the landscape, and his father asks if he would be willing to draw him too. This is the dialogue after that:

人間は書かない (I don't draw people.)

なんで？ (Why?

人間は嫌いだ 基本的にだけど
(I hate people. Basically, though.)

I was wondering if 基本的に meant:
1) I generally don't like people, but there are some of them I do like.
2) That's the main reason why I don't draw people, but there are other reasons too.

Any ideas?

Thank you very much!
