It seems to me that some sweeping generalizations have been made for which no proofs have been provided, such as, "[W]e have been told of dog-fighting rings; we have been told of starving horses. But the worst cruelty seems to be to dogs. Many are chained with no shelter all winter; shot, run over, left to struggle for survival with broken limbs and bodies while being attacked by packs of hungry dogs, slashed with knives, drowned, hung, starved and tortured..."

You haven't said what you have personally seen and a lot of what you write is only what you have been told by others.

I am not convinced that indeed you are not racist.
