Why's that relevant? The point (unless I'm misunderstanding badly) is that the ban is there because some Christians wanted it to be, that the great majority of the non-Christian population would likely prefer it not to be there, and that this is therefore an example of a Christian rule being enforced on people who are not Christians.
The fact that a small fraction of the non-Christian population might be happy enough for the rule to be there is irrelevant. If there were a law requiring everyone to go to church on Sundays there would probably be as large a fraction of the non-Christian population in favour; it would still (obviously, no?) be an example of a Christian rule being enforced on people who are not Christians.
If there were a law requiring everyone to go to church on Sundays
There have been such laws in the past, but is impossible for there to be such a law in the present day. There aren't enough Christians to pass it or enforce it.
