Hi! awesome post! As a Libertarian, I also enjoy reading Voltaire and especially Locke. As for freedom fighters today, I would say they have become rare but not extinct. I would consider personalities such as Dr. Jordan Peterson modern freedom fighters. In general, I would say anyone who dares to voice his opinions despite the possible repercussions that may occur legally or socially, could be called a freedom fighter. Although one must add that unfortunately, there are individuals who advocate for freedom with the opposite intentions. Thanks for the read anyway and have a nice day!
