Sadly, they don’t. Genetics seems to be the main thing predicting behavior – but to liberals’ credit, the environment still plays a huge role. What kind of argument is it to say that an abused dog is going to be the same as one that is treated well?
But the genetics argument gives a green light to some really obnoxious WN’s and their movement which they see as persecuted – and in fact it is indeed persecuted – because the Establishment in the West is highly PC.
And finally, even if genetics plays a huge role in things, is the info being used to lovingly help people or to flame hate? Of course, it’s used for the latter because the WN (or similar) movements are all about separation, venting anger, etc..
