Such a good post PZ.
DH and i have talked about this a number of times - when to really kick up a hoohaa, and when to say something short and sweet and let it pass. DH is surrounded by ridiculous nonsensical racist rantings. He is infuriated and sickened by it, but the best he can do is state his position/beliefs and walk away. One guy says loads of 'foreigner' racist bollocks and his wife and her daughters are Thai??

We all need to show our children its not ok, and hopefully we can change their future.

Don't get beaten down by it. But you don't have to always get fired up either. Ignoring it is not right, so just find a peaceful and calm controlled way to state your case. If we all do it, we might just find that there are more people who agree with us, but don't have the courage to say it themselves.

Great post PZ. xx
