Clint Bolick has an interesting piece defending freedom of asssociation as a cornerstone right. Worth quoting:
Gays and Lesbians for Individual Liberty, represented by my organization, the Institute for Justice, submitted a brief disdaining the Boy Scouts' discriminatory policies but defending their right to maintain them. The brief argued that "[w]hile a creeping infringement of [freedom of association] would harm all Americans, it would particularly threaten the welfare of gay and lesbian Americans, who have historically suffered when government has not respected citizens' right to gather together free from government harassment."Posted by Greg Ransom
