Political labels only have meaning in the context of a given time and place. What’s moderate in one place and time can be extreme in another. What’s right-wing at one place and time can be left-wing at another. (And in both cases, the converse is also true.) Obviously the person you are replying to meant those terms in a contemporary US-centric context - a “moderate” in the US is likely to be a fair way to the “right” by the standards of some countries, and a fair way to the “left” by the standards of others.
