It means "I recognize that this is a complicated topic, but I'm just going to discuss it in a simplified and perhaps slightly incorrect way."
If you ask me:
"Why don't you ever go to that restaurant?"
I might answer
"Because I disagree with the chef's political views, and the culinary style doesn't match the aesthetics of the decor. However, I feel uneasy about not going there, because the waiter is friends with my sister."
OR, I could just say
"Oh, you know, I just kind of don't like it."
Adding "kind of" means "I am able to talk about this in more detail, but I'd rather not."
