It is complicated. Most people in Poland do consider themselves part of Europe, sometimes even part of the West. At the same time people in Poland often contrast the West (as in Western Europe and US) with Poland and perceive west as something different and better. It is sort of post colonial mentality but with a twist, because it is not tied to race. This idealised “West” is often very far from real situation in Western Europe. On the other part of the spectrum you got polish conservatives who see west as degraded and fallen. They used to say things like: France no longer exists. Meaning France is not what it used to be; it is not true west because they lost the spirit of real west.
