The Gülen Movement has significant effects on society so is it not conducting political action, even if it is not party political?

No. Political action and community service are different. Political groups with different political outlooks, worldviews and goals, work for their distinction, separateness and superiority over others. They work self-righteously for positions in a political environment, to be seen and elected. Their separateness and superiority should not be confused with service-networks, which operate altruistically to offer what is lacking in a society, and in which people or groups efface themselves and work without being named or acknowledged. The intention is not to be seen or elected. Quite the contrary, people contribute anonymously.
