It's not an exact comparison, obviously, and how much of a comparison in regards to whether its a good or bad one is really just matter of opinion.
However, there are similarities:
- opponents of integration cited that allowing blacks to serve alongside whites would damage moral. The same is being said with gays.
- Same with unit cohesion
- discrimination can or does exist for both minorities and gays
- Many of the problems are rooted in assumptions about gays and minorities.
I read this in an article on the subject: "Most people think of racial identity as a matter of (racial) status, but they respond to it as behavior. Most people think of sexual identity as a matter of (sexual) behavior, but they respond to it as status. Accordingly, people who fear and dislike blacks are typically preoccupied with the threat that they think blacks' aggressive behavior poses to them. Hence they're inclined to make exceptions for the kindly, "civilized" blacks: that's why "The Cosby Show" could be so popular among white South Africans. By contrast, the repugnance that many people feel toward gays concerns, in the first instance, the status ascribed to them. Disapproval of a sexual practice is transmuted into the demonization of a sexual species."
Interesting note: when Truman issue in the integration order, 63% of the american public was against it.
There are also a lot of differences, including:
1. People can and do change their sexual preference. We have a number of examples of straight people becoming "gay," and then straight. People getting married, having kids, and then having the "gay" epiphany.
2. A person cannot change his or race. You have it at birth and at death. You can't decide to be Asian one year and white the next, unlike people in the GLBT/gender identity community.
3. There are deeply rooted objections to the GLBT/gender identity classifications that are not based on "fear." The conduct was actually illegal for most of our country's history.
4. It's unnatural behavior, unlike race, which is innate.
5. There are well founded moral objections, based on explicit scriptural references and the majority of the country is Christian.
