I don't really care if a cross-beam from the World Trade Center gets put in a museum. I find myself objecting to a lot of the lawsuits that American Atheists bring out, carrying the flag of the ACLU. I love the ACLU and appreciate that American Atheists can be credited with getting the word out that closet atheists or skeptics aren't alone, but there are more important things to be fighting against.
A bunch of people in a country made up mostly of Christians found comfort in a cross at the World Trade Center after a horrific, terrifying and tragic event. Regardless of the fact that "it's a religious symbol," it's there. It's part of that day, it's part of that history. Bring to the museum some things that people from other religions (or non-religions) found comfort in and have a multitude of symbols that everyone can look at and say, "Wow, different people find comfort in different things." That, to me, is win-win. This lawsuit just isn't worth it when you have places like Texas that want to pull Thomas Jefferson out of their textbooks and put in John Calvin in his place as a Founding Father. It's nothing but a distraction from the fact that women in some states are being forced by law to carry zygotes in their bodies because that state has determined that it can decide and legislate moral and philosophical questions about the origin of life based on a book written by superstitious desert nomads from the Middle East.
Humanism, secularism and atheism should be concentrating on these glaring issues facing us today, not possibly setting a legal precedent by losing cases like the WTC museum lawsuit. It's irritating to think that real church/state separation issues are getting less spotlight than the bickering of street names ("Seven in Heaven") and cross-beams. If secularism is going to be a movement, they should start by picking their priorities.
