I have heard multiple FB posts and meme's about how "We put 'In God We Trust' on our money and 'Under God' in the Pledge of Allegiance in the 50's to separate us from 'Godless Communists.' " And how Baseball players didn't stand for the Anthem until WWII and NFL players didn't come out for the Anthem until 2009.
Think about this: Very, very rarely is something done right the first time. The Constitution is one of those things and we still have "improved" it 17 times (the Bill of Rights was 10 at once and the 21st Amendment repealed the 18th Amendment).
Think about plastic sandwich bags. they were invented in the late 50's, the kind where you had a "flip-over" top. It took about 15 years for the Ziploc bags to become sandwich bags. It took 25 years after that for someone to come up with the idea we have now, which is to make one side of the bag taller than the other, making those bags easier to open.
Besides, "We've always done it this way/We've never done it that way" are two of the seven signs of stagnation. Doing things a certain way because we've "always done it that way" without a good reason why we are still doing it "that way" is stupid.
If you can't articulate a good, sensible reason why we do things a certain way, find out why. Once you can explain why things are done this way now, then and only then you can articulate why it should be changed.
Change for the sake of change is never good, Change for the better should always be encouraged.
