But the probability of changes is there , and when we can decide we want our changes to be justified Right , that ' s being reasonable , not simply being opposed to any foreigners or racist . If your view is that it can be reasonable to oppose certain influxes of foreigners , that ' s different than tendency to reject foreigners . Ask Australian aboriginals or Native Americans . This really isn ' t comparable , we know where foreigners are coming from and they aren ' t bringing in more advanced weaponry or illnesses we ' ve never been exposed to anymore . when people aren ' t even prepared to give them a chanceThe thing is it requires effort . It also requires effort to oppose them , and in that effort you ' re also risking passing up on positive results of accepting them . Either way there is effort and risk . It ' s just whether you ' re being unreasonably accepting or opposed that ' s the issue . But if you narrowed your view down to reasonably opposed we get to a point where it ' s true by definition it ' s of course reasonable to be reasonably opposed .
