since bigotry has nothing to do with genetics as far is known to the scientific world, bigotry
and Darwinian natural selection have nothing to do with each other. as Darwinian natural
selection is based on genetic traits that would help you adapt to the environment better
then others in the same species.

before it was like we have to adapt to the environment, nowdays, we adapt the environment to us.

Bigotry implies that one is in a state of prejudice, one that is close to opinion or lifestyle of others although proven wrong. Although this can exist as a form of self defense for an individual or a community since they choose to protect themselves from what seems to be harmful ideas of other s(ie, technology, religion etc), bigotry is rather the exact opposite of Natural Selection. Darwin implies that species mold themselves to adapt to changes in their environment it is " a battle of the fittest", so if one is a bigot how can that individual change or adapt. Change requires an open mind and so is adaptation, therefore bigotry and Darwin's theory are two opposing ideas.
