No, that is not true! Liberals, progressives social democrats and even socialists to a small extent believe in market mechanisms to a certain extent now. It is not either or: either a pure central planning commie or a pure free marketer. There are degrees. You are lost in a false dichotomy. There is also disagreement about what exactly is freedom, but I think I have given you enough to consider (or be closed-minded and not consider it - whatever you prefer).
