The government is never more liberal than the people

It is impossible for the government to impose liberalism on the population... assuming we are in a democracy. If the people do not want liberalism they will not vote for it. It is only possible for the government to impose tyranny on the people which they do not want by means of the electoral system being unfair. Tyranny by definition is a lack of choice and so it can never come from too much democracy. If liberalism is possible under fptp then it is equally possible under pr because for it to exist under fptp means a sufficient number of people are prepared to vote for the liberal party and they cannot be defeated by the alternative. If the electorate is willing to behave in this way under fptp then pr would be no threat to freedom. And if they do not vote for liberals under fptp then there is a chance pr could offer them the alternative they need to reject tyranny. Fptp is never good and sometimes bad... for it to be good would mean that the government is more liberal than the people which is impossible. The government is never more liberal than the people and so pr is preferable.
