I want freedom of thought restricted only by reason. "Liberalism" has its own thought prison so how does it support liberty?
Liberalism comes from the word liberty, but it's not in its core to defend liberty itself, it's more in defence of like I said, changement from the past and present dogmas/laws/customs.
Liberalism is a very broad concept, it does in countries like Iran mean the defenders of reformist values against the very conservative dogmas of the country. In China it's the people that are against the mass surveillance of the internet. In Russia, against arbitrary laws that allow men to beat women. In Western countries, they are against laws that attack transgender rights for example.
It's a very, very broad concept, specially in that freedom side. Being against racial jokes isn't a way of defending the freedom of black people not to be discriminated against? Or are you taking away the freedom of people to be racist?
Either way, a liberal will be the one defending the first position, and a conservative the second, always. Why? More of a definition thing. The first one is a change of the system, the second one the defence of a common thing of the present and the past (aka racism).
It's a matter of definition, being liberal or conservative, not an ideology by itself. You can be conservative on X policy and liberal in Y idea. It's narrowminded to be against conservatives because of Ted Cruz, or being against liberals because of some stupid SJW...
