The fact is however that people today in democratic societies already celebrate whatever they wish anyways, including making up holidays that never really existed or adoption of and redressing / holidays that different cultures incorporated into Christianity hundreds of years ago as the early Church expanded in the late Roman Imperial Period and beyond.

I see no reason why if the majority of the people in a given region wish to celebrate their predominate common holidays publicly that the community cant display decorations with taxpayer money etc if they wish.

I see no reason whatsoever why everyone else has to stop doing what they do because some numerically inferior fringe subsection/minority of atheist hypocrites want to have a hissy fit whenever anyone mentions anything associated with religion.
