In France there is no mix of religion and politics because is very private. For example the French president would never say his religious beliefs and it can be considered rude to start a conversation about it in a party or dinner.
Besides France is less religious than other countries such as the United States, they have religion but is a personal choice. The term "Laïcité" means that the state is separate from the church but all the religious beliefs are treated equally but also including having no religious beliefs.
This term can be considered as a value that represents beliefs.
