在美国,对于非营利组织而言,表达自由远比结社自由更为重要。表达自由保障了非营利组织的资源筹措,限制了官方对非营利组织的表达活动的任意限制,提高了官员及公众人物对非营利组织提起诽谤诉讼的门槛,从而成为美国非营利组织发展的宪政基石。 In the United States, freedom of expression is far more important to non-profit organizations than to freedom of association. The freedom of expression guarantees the non-profit organization’s resource mobilization, restricts the official restrictions on the non-profit organization’s expression activities and increases the threshold for officials and public figures to defame the non-profit organizations and thus becomes the constitutional government for the development of non-profit organizations in the United States cornerstone.
