It is usually implied that when people talk about their experiences, they talk about things they have personally experienced.

If the discussion is about the general “left/right” divide, and you are speaking more specifically about the left/right divide in your own country, it make sense to indicate that and what country you are from (of course, you’ve avoided mentioning what country you are from).

I wonder why did you think I lived in the US in the first place.

I wonder why you weren’t more specific about what you were talking about when we are talking about the general left/right divide.
