At what point did the term change for the negative?
When the conservative election winning professionals blabbed about it to the uneducated fox news viewers.
To answer the OP.
Bitcoins are not going to change the way society operates but if they do, great. If you sit down 1 on 1 with a liberal ask them how they feel about the value of the dollar I doubt your answer would be much different then that of a "conservative". You're implying an awful lot about liberals and come off as rather elitist in your main post.
