Liberalism is a political philosophy-ideology favouring centrist-laissez-faire economics, willing to comprimise a bit. Additionally,
liberalism advocates for the invidualist freedoms, including democratic rights. They support a democracy. Liberals are also advocate of
separation of church and state, open-disscusion,
Social Progressivism and centrism.
Liberalism has it's own
radicalized variations, not
centristic. One such radicalized variation is
Libertarianism. In the US, people confuse liberals with Social democrats, democratic socialists, and anyone not a conservative. Liberals, however, differ from Social democrats in not supporting too many government funded programs, being more to the right. They are, although, willing to make comprimises with them and conservatives.
