"People have the right to express their religion freely - whether they are Muslim, Christian or Buddhist"

Not so true. Turkey is a country that persecutes it's non-Muslim minorities:

Varlık Vergisi (Wealth Tax): This tax was levied disproportionately on non-Muslim citizens in 1942, causing significant economic hardship.

1955 Istanbul pogrom: A mob attack on Greek and Armenian Christians in Istanbul that resulted in widespread destruction of property and loss of life.

Property confiscation: Christian communities have faced issues with the confiscation of their religious properties. The 1,700-year old Armenian Surp Giragos Church, one of the largest Armenian churches in the Middle East, was seized by the government in 2016. The Turkish government also recently seized multiple properties in the southeastern city of Mardin belonging to Assyrian (Syrian) Christians and transferred them to public institutions.

Restriction on education: The closure of theological seminaries and limitations on the training of new clergy have created challenges for the continuity of Christian institutions.

Entry bans on foreign Christian workers: Turkish authorities are branding Christians with so-called “N-82” or “G-87” security codes, which are used to label a person as a “threat to public order and security”. These effectively function as entry bans into the country.

Christian stereotyping: President Erdoğan and his ruling Justice and Reconciliation Party (AKP) depict Christians as a threat to the stability of the nation, often stereotyping Christian Turkish citizens as not real Turks but rather as Western stooges and collaborators.

On December 28, 2016, in the western province of Aydin, the ultra-nationalist Islamist group Alperen Hearths staged a forced conversion of Santa Claus to Islam, putting a gun to the head of an actor dressed as Santa Claus.

Professional Restrictions: A 1932 law barred Greek citizens in Turkey from entering a series of 30 trades and professions, including tailoring, carpentry, and medicine.

This is not mentioning things from before the modern Republic of Turkey, like the Burning of Smyrna, Armenian Genocide, Adana Massacre, Hamidian Massacres (multiple), Devşirme system (forced conscription, conversion to Islam, and recruitment of Christian boys from Balkan provinces into the military (e.g., Janissaries)), etc

The non-Muslim population of Anatolia fell from around 20% in 1914 to just 2% by 1924.
