Should we cancel the national day of prayer?

The national day of prayer is a day where you give thanks to your god. It doesn’t bias any form of religion and it isn’t mandatory. A lot of people don’t even know when the national day of prayer is. So why get rid of it? About a month ago a federal judge from Wisconsin said that having a national day of prayer violates the 1st amendment. If that is the case doesn’t having in god we trust in the pledge of allegiance? Or when people ask god to bless America? Doesn't those have to deal with religion? We are in fact suggesting that there is a god and that we as a country acknowledge that. America was always a place that no matter what your beliefs are you have the freedom to practice that religion openly. Now president Obama, his administration and a federal judge from Wisconsin want to cancel the national day of prayer all together, saying it violates the 1st amendment clause. When this county was originally established by the pilgrims who were mostly puritans, they wanted freedom from the English church and a place where they can practice their religion openly. That’s how America has been since the puritans, a place where no matter what your beliefs are you have the right to practice them openly. That’s why we have the Jehovah witness knocking on your door on Saturdays. Is it all that terrible to give a religion a day where they think that they should spend some time and thank their god for whatever they want? Even an Atheist should be able to except that not everyone shares their beliefs and they have the right not here in America
