Western society was built upon the idea of keeping religion out of politics and secular society as a whole.
Demonstrations of religious belief in the public only serve to divide a country and promote hostility between different ethnic and religious groups. In order to keep society stable, religious fundamentalism should be confined to places of worship and personal homes.
Maybe a hijab should not be considered a big deal because its just a piece of garment that is associated with a persons religion and I do not think it is fair tell somebody what they can or cannot wear. I do not think it has an influence on secularism.
