A "right" is defined as: freedom to act within the Socio-economic context free of initiation of physical force. Hence...the "right" defines what can be done by people. The exercise of a right never harms anyone.
Recently...though...the concept of "right" has been coopted by the would-be master. The manta heard is: MEDICAL CARE IS A RIGHT. Somehow...a person's illness is a call on the wealth of everyone...and...to insure the medical bills are paid...a would-be master is required to ferret out and grab such wealth so it might be handed to the poor and needy. Such a "right" subsumes even the right to life...reducing the population to herd-format...easily directed...and...always imperiled by whatever "right" the mob might wish.
