Danger of dogma  Having a fixed set of fundamental human rights makes it harder to adapt to changing circumstances. As we have already seen conceptions of human rights vary by culture and time, and should be properly seen as a product of those specific factors, not as universal fundamentals. What was seen as a 'fundamental right' in the 18th Century may not be appropriate for the 21st, and what is seen as a right in the 21st Century may be actively harmful to recognise as a right in the 24th. For example it could be argued that the right to keep and bear arms was more useful in the America of the 18th Century, when there was no police force and hunting for food was more important, than in the 21st Century, where it could be argued that gun ownership results in higher gun crime rates for America than for other industrialized nations. [1] Enshrining rights as 'fundamental' makes it much harder to remove or modify them as circumstances change and they become less useful.
