Yes, she has an agenda. She'd like the symbol of her husband's faith to adorn his gravestone at Arlington --as the followers of 37 other "authorized" religions are allowed to do.
The only thing disrespectful is the way her husband's religion is dismissed as unworthy of a symbol upon his grave.
Kinda reminds you of the Taliban, doesn't it?
Her husband's pagan RELIGION isn't worthy of anyone's respect or honor, but IMHO the MAN HIMSELF is worthy of his nation's respect and honor because he gave his life for his country and for his fellow Americans' freedom to worship the one true God in the manner we believe to be correct.
I'm very sorry that he apparently died as a lost nonbeliever in the Lord Jesus Christ, but that was by his own free choice.
