The individual has no group lobbying for him, no party representing him. Movements, parties, churches, sports teams, associations, and all other "group-think" entities are, by definition, "collectivist". They unite people around common values and goals, not individual ones. There is nothing inherently wrong with any of them. In fact, they are an expression of "individual" choices.
Still, there is the danger that these "individual" choices made in a "group-think" environment will trump what is the essence of political freedom - the ability of the individual to live his life relatively free of unnecessary constraint. This was clearly in the forefront of the American founders' minds when they used the language "...endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
Life, Liberty and the Pursuit of Happiness are all explicitly "individual" matters not societal ones. The purpose of law, the meaning of freedom is the protection of individual rights. This is not to say that "social justice" is an invalid concept, but the subjection of the minority to the majority is, and always will be, tyranny.
