That's not exactly true. Hate crime laws do nothing but give harsher penalties for existing laws (battery, murder, etc) when they are committed while disparaging a person for their race, gender, sexual orientation, etc. Now, while there aren't many instances of "straight-bashing" or "male-bashing", there are plenty of examples of black-on-white crime that is explicitly racially-driven, and they almost universally reject applying hate-crime statutes. The most egregious and stunning example would be the Wichita Horror.
Secondly, many anti-discrimination laws do NOT include white males, as they are explicitly written to guarantee others the same rights as white males. Further, their application is almost universally for every other group. (Shall we look at the percentages of cases that favored white-males, and whine if they aren't close to the 33% population figure?)
Finally, there are multitudes of discrimination laws (Affirmative Action being the pre-eminent example) that allow institutions to discriminate against straight-white-males with the sanction of law. When any other group is similarly overlooked for circumstances of their birth, they have legal recourse today. I, as a straight-white-male, most assuredly do not. My life-long dreams of being the president of the NAACP, a few womens' colleges, NAMBLA, GLSEN, etc will never be realized, even though those groups, statistically and explicitly, shall always prevent "my kind" from achieving that position. I can't sue when publicly-offered scholarships refuse to consider "my kind", but a black person can sue if I were to privately offer a whites-only scholarship.
You can say that I'm included in the discrimination laws, but that is just as morally dishonest and obtuse as proclaiming that blacks were treated the same under law in the South the day after Jim Crow Laws were repealed.
Kansas has no hate-crime law. I don't suppose you thought to check on that before bringing up the Witchita murder case, did you? And for the record, the two guys who did it were convicted and are on death row. Lack of a hate crime law really impeaded justice in their case, didn't it?
