What stage of genocide is "Propaganda surfaces: “Armenians are siding with the Turkish enemy (Russia)”. Intermarrying is forbidden. "

This is the second stage of genocide.

Explanation:

Once the first stage went on well, the second stage was waiting for implementation. Now that there was a clear distinction between the Turkish and Armenians in the eyes of the public, the government started with propaganda, using symbolization to vilify the Armenians and to give reason to the Turkish population to dislike or hate them.

This was done by spreading propaganda that the Armenians in Turkey are siding with Russia. Russia has been the biggest Turkish enemy for several centuries, so this immediately caused fear, insecurity, panic, and aggressive behavior from the Turkish population. In order to stop the spreading of Russia's influence through the Armenians, intermarrying became forbidden.
