Grieve, as a student of post-bellum American history, I'm going to have to disagree. Sorry. I guess that's the position we're at. Oppression is oppression, though, whether it is against one person or one hundred thousand. But, if I had to be a gay man in the 21st century or a black man in the 19th, I would most certainly choose the first one. Hands down.
All that said, your ignorance of anti-black violence astounds and disheartens me. Many more than "a select few" blacks were lynched. And lynching blacks started before the KKK did. Lynchings were often public events, carried out on Saturday or Sunday afternoons, and almost everyone in town would attend.
Even today, in the United States, anti-black bias has been the most frequently reported hate crime motivation. (African-Americans constitute the second-largest minority group; Hispanics being the largest). Of the nearly 8,000 hate crimes reported to the FBI in 1995, almost 3,000 of them were motivated by bias against blacks. Other frequently reported bias motivations were anti-white, Jewish, gay, Muslim, Asian, Native American, and Hispanic sentiments.
Tolerance for homosexuals, however, is on the rise. 49 of the 50 Fortune 500 companies, for example, include "sexual orientation" on their list of non-discrimination policies, and over half of them give spousal rights to homosexual couples.
In terms of support of public policies, according to the same 2001 study, 76% of the general public think that there should be laws to protect gay and lesbian people from job discrimination, 74% from housing discrimination, 73% for inheritance rights, 70% support health and other employee benefits for domestic partners, 68% support social security benefits, and 56% support GL people openly serving in the military. 73% favor sexual orientation being included in the hate crimes statutes. 39% support same-sex marriage, while 47% support civil unions, and 46% support adoption rights. Much higher numbers than you would have ever had.
