Since when libertarianism and human rights have been on the opposite sides?
I dunno about opposite, but certainly in opposition on certain points: http://www.un.org/en/universal-declaration-human-rights/inde...
"Article 25.
(1) Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control. (2) Motherhood and childhood are entitled to special care and assistance. All children, whether born in or out of wedlock, shall enjoy the same social protection."
Obviously, this means taking from those who have to give to those who have not, which is pretty strongly opposed by the right-libertarians.
a bunch of the others also conflict with right-libertarian principles; like article 24 limits working hours and says I should get some paid vacation and 26 says elementary education should be free (and compulsory)
Right-libertarians generally don't believe that you have a right to any of those things if nobody else wants to give those things to you.
Generally this is talked about as the conflict between positive vs negative rights, or human rights vs property rights.
I mean, you could come up with some version of "human rights" that doesn't include the right to food, shelter and medical care... but you could also come up with a definition of libertarianisim that includes some form of welfare for everyone. I personally know several people who identify as libertarians who also support universal basic income...
I'm just saying, that's not how those words are usually used. Usually 'human rights' includes some kind of positive rights, and usually 'libertarian' means 'primarily focuses on property rights'
