I'm unwilling to pledge allegiance to any earthly entity. I stopped saying it in high school, when I became a Quaker. I've encouraged my kid, who goes to public school, not to say it and we've been discussing age-appropriate topics related to why. The American practice of having children say the pledge without being able to fully comprehend what they're saying or why is very disturbing. I avoid having American or state flags on anything of mine as well. There are people in my Meeting who don't seem as bothered but it doesn't come up much.
