It's quite normal as we grow up we become more conservative, especially successful people - we want to continue the success that was based on values we grew up with. That's why conservativism is associated with belief in authority - you need authority to enforce the values of the past.
So when you grew up, you perceived freedom of speech as a good value because it meant freedom, and now you perceive it as a good value because it was there when you grew up.
However, liberals moved on, and found other issues that concern human freedom, which were neglected before. So for instance, there is freedom to have a different sexual orientation, and be able to express it. Conservatives disagree with that value because it simply wasn't part of our culture in the past.
(Progressives - or perhaps socialists would be more fitting name - are based on another value, namely inclusion in the community. They are distinct from liberals.)
