I agree with you Lilygran. It's impossible to get through a day without some form of speech or behaviour that has religious influence being utilised. Likewise, the influence of anything non-religious from our past that has relevance today. That's different from choosing to use religious speech or behaviour, though. I regard much of it as benign, and when someone says 'god bless you' or I walk into a supermarket and there is a school brass band playing hymns, as there was last weekend, it doesn't bother me. It's when it's imposed on me that I start to bristle.
Now I'm retired, I don't have to sit in community liaison meetings where the local priest, chief police inspector and a local do-gooder insisted on having the meetings in the catholic school hall and starting with a prayer, after the tea and biscuits they would drag people in for first. Turning up to meetings with my Muslim colleague, the specialist liaison worker, was some challenge. She would politely sit there with me and we would express our frustration another time, in an effort to move things on, but it still happens today. Those meetings were about crime in the local community, but the organisations involved insisted on bringing religion into it. They wouldn't accept the invitation to meet in the mosque's meeting room, or a probation office.
My daughter has two primary schools nearby, one catholic and the other C of E. she just wants her twin girls to go to a decent school in due course without too much travel and fuss. She's excluded from the catholic one as she doesn't fit their criteria, and the C of E school will accept her but her children will be required to attend church or Sunday school several times before being enrolled. Or she can just uproot them and move house. We feel that this is discrimination. Children have to be educated, but the choice is restricted. I don't know how children with a different faith are schooled in that neighbourhood.
We have a lot of outdated laws and customs that are so ingrained we will never be free of religion. To say atheists are anti-religion misses the point. It's a bit like saying we are anti being beaten round the head with a cricket bat.
