There is an assumption that if a white person attacks a minority, that it was because the person was a minority. I'm going to go out on a limb and assume that sometimes a crime isn't racially motivated, even if it is an evil white man committing it. However, if a minority commits a crime against a white person, the first assumption is that there are "deeper sociological issues" that caused it, rather than maybe the perpetrator was just a racist piece of shit. The numbers from the FBI seem to confirm those biases.
Perhaps the fact that I grew up on the east side of Detroit has allowed me to see some realities you may not be privy to. No big deal, we all have different opinions based on our perceptions. In my neighborhood, most of the "hate crimes" were perpetrated by blacks, against whites (and a few asians). Had I grown up in Alabama in the 60's I'm sure I'd have a different take on things, or if I'd grown up in the suburbs and only had the media to shape my experiences, I'd probably have a different take on things too. I spent the first 20 years of my life as a "minority", with all of the fun that goes along with that, and none of the legal protections that exist for everyone else, so I'm basing my opinions on reality, not some shit I saw on TV or something I read in some bullshit magazine.
