It's just the overall thing in general of the liberals wanting to take away traditions. Now, do I dare bring up the one about the Pledge Of Allegiance not being required in schools? Is there anything I can post here that others will actually agree with? We need more republicans to post in here!
We have a Republican who posts here rather frequently. He doesn't always agree with you.
I consider this particular tradition to trump the Pledge of Allegiance: "Congress shall make no law...abridging the freedom of speech." That's from the First Amendment. Also, the Pledge of Allegiance never said "under God" originally. That was added much later - anyway, you should be allowed to abstain from it if you want to. The government can't force you to say it. That's what freedom of speech is all about.
Conservatives changed a much older tradition when they made In God We Trust the motto. They changed it from the one chosen for the USA by the founders: E Pluribus Unum - From Many, One. Most liberals who want to get rid of In God We Trust want to go back to what Washington, Jefferson, et. al selected for the USA, and toss a knee-jerk reaction to Communism.
Anyway, no liberal really wants to take away a tradition...I can't think of a single person who, say, wants to dump the Pledge of Allegiance altogether - they just want a child's right to not say it to be upheld. They don't want the USA to not have a motto - they want the USA to have their original, more badass motto. Lots of traditions in the USA will continue, because there's nothing wrong with them. Here's a short list off the top of my head.
The Super Bowl and World Series will still happen every year.
The President of the USA will still say the Inaugural Oath every 4th Jan 20th. He or she will likely still add "So help me God" at the end, which is a personal choice.
Army will still play Navy.
The Boston Marathon will still be run.
Fireworks will fly every July 4th.
The Star-Spangled Banner will still be the national anthem of the USA.
George Washington will still be considered the founder of the country.
People will still go to church on Sunday, temple on Saturday, and pray to Mecca every dusk.
Americans will still believe they live in the greatest country on earth, despite every piece of evidence to the contrary.
Liberals like you describe simply want people's rights to be preserved - the greatest American tradition of them all. Let me finish with another quote. This one you might have heard of..."We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
