Ronald Reagan based his political career on doing exactly what I've described. His "moment of opportunity" came with the riots in the 1965 Watts riots in Los Angeles. The following year, he was elected Governor of California. In the ensuing years, violence against blacks and Chicanos increased.
Now we have politicians like Rick Santorum, and their followers, who are convinced that marginalized people are nothing but sponges for their tax dollars, and that any violence against, or disease contracted by, LGBT people is "God's retribution" or some such thing. People who are afraid of losing their communities and countries to "others" are receptive to the messages of folks like Santorum, who may actually beat Mitt Romey--whose father was a Governor of Michigan--in the State's Republican Presidential primary.
Such an atmosphere cannot make things safer for any member of a "minority" group, especially trans people. The irony is that the people who are convinced, or can convince others, that we are some Levitical "abomination" that will destroy the fabric of this society also see us as expendable and will attack us rather than others who are more numerous and have more resources.
I really hope that neither Detroit nor any other city will experience another murder so brutal and senseless as that of Coko Williams. Hey, I hope not to be the next Coko Williams! And I hope the authorities in Detroit take the investigation of her murder more seriously than their counterparts in other places have taken the brutal, grisly killings of too many of our sisters.
