That doesn't make them Christian. When they win an election it does not mean the country has become more Christian.
He (Erdoan) quotes Islamic values and acts on them in the name of Islam. And yes, if the population of a country elects a religious leader that runs on religious values, it DOES mean the country has become more religious.
Are you saying that Islam is defined by the outcome of Turkish elections?
Islam, as all religions, is defined by the values of the people that make up the faith and the leaders they elect / appoint to project those values. This, as opposed to how some random guy on the internet defines it.
How do Muslim's vote in the U.S.? If they vote Democrat does it mean Islam supports trans-gender bathrooms? If they vote Republican does it mean the Islam fears and hates it's followers?
I personally vote with the issues not based on the D/R in front of the candidates' names. To be honest though not even sure what you are getting at.
