The United States has utilized multiple forms of liberalism throughout its history

Modern liberalism is not completely collectivist; nor is it completely individualistic. It has elements of both doctrines. The same is true of conservatism. Neither view provides a coherent approach to politics, built up from first principles. Instead, they both reflect a process that is akin to picking items from a dinner menu. What is chosen is a matter of taste rather than a matter of thought. Just as people with similar tastes in food tend to frequent the same restaurants, people with the same tastes in politics tend to vote for the same candidates.

Humanitarian wars are also commonly associated with modern liberalism; these wars are fought with words, unlike other wars. They are intended to help support the people who cannot support themselves and to stand up for the rights of people to use the state to their benefits. Modern liberals are also fond of the idea of mixed economies; they believe that there should be less definitive class separation and that there should be a strong mixture of people from different backgrounds combined together in an economical society.

Unlike traditional liberalism, there is a certain element of tyranny within the modern liberal movement. In the past, liberalism was used to literally liberate people from the rule of kings and tyrants. Modern liberalism is now imposing its beliefs onto people who are not interested in focusing their lives around how their state can help them; it is a forced movement that is functioning more like a tyranny than any other liberal beliefs have ever done.

classical liberalism features
all human beings have inherent dignity and worth

all individuals have inherent natural rights; including life, liberty, and property

governments and social arrangements are human constructs; their justification is the establishment of order, to promote justice, and to protect and enhance natural rights

While humans are equal in rights and dignity, our inequality in talents, interests, and other qualities is a valid and necessary aspect of the human condition.  Thus classical liberals oppose leftist attempts to force equalization of condition or result.
