Legislating the teaching of creationism in government schools, or legislating school prayer, certainly is forcing your religion on others. Your children can learn about creationism in Sunday School or at home, and you can pray with your children all you want at home. Yet there are constant efforts by the religious right to get both into government schools.
I object equally to the left trying to remove any mention of religion, especially by students. Students have freedom of speech, and should be free to pray in school, form thier own prayer groups, recognize God in thier graduation speeches, etc. I even think its fine for the school to put up Christmas decorations, and hannakah decorations, etc, as long as they do not discriminate in favor of or against any religion.
