I believe the differences in cultures give rise to tribalistic attitudes that provide a bond within each group, against its perceived enemies.

False logic, possibly through sloppy thinking, then compounds the argument by basing views on stereotypes.

Diversification of species is what has allowed single cell organisms to evolve into human beings I think.

So when an argument is promoted concerning purity of "blood lines", etc a fear of change and its consequences is being demonstrated.

As Voltaire once said "I may disagree with you, but I shall fight to the death for your right to proclaim your beliefs" (paraphrased perhaps).

The dilemma arises when hate is exploited to incite unjustifiable acts. It is this dividing line that should be used recognise where attitudes are intolerable.

"Evil happens when good men/women do nothing"

However, knowing what I should do and actually doing it requires moral courage and is the greatest form of bravery in my book.

Take heart! I think you have done what I know I should do also, Trish.
