I always try and read and absorb what people write here - perhaps in this case i didn't write enough to explain. So, NO, I wasn't talking about 'cross breeding humans' .. I was talking about the difference between the cross-bred dogs themselves and their place in society versus the issue of those of us (humans) who allow cross-breeding to happen (in dogs) - ie, backyard breeding etc. I'm sorry I wasn't clear .. so no, certainly wasn't talking about human genetics etc etc.
Hope that clears things up ..
Best wishes, SH
