It has bugger all to do with either history or philiosophy.
The point is that people such as yourself try to justify the wrongs of today by pointing at the past like petulant children who point and say "but Johnny did it", it just doesn't wash as an excuse.
The only way to make changes to the future is to accept the wrongdoing and correct it , instead the majority of people are happy to bury thier heads in the sand and pretend they don't see the truth.

I personally don't really care much for mankind and to be brutally honest I believe we could do with a few billion less people , I do however have an obsession with the truth.
Denial of our faults only allows us to keep believing we are perfect and we most definately are not.

The dirty tricks our goverments use will always come back to bite them or future generations in the arse.
