On my post about atrocious language in a television report about two transgender criminal suspects. The article referred to them as "perverts," "freaks," and "bosom buddies." Some of the commenters on the post seemed to argue that the severity of the crime (sexual in nature) made it okay to refer to the alleged perpetrators in derogatory language.
It doesn't become okay to be bigoted just because the targets of one's bigotry did something wrong. Would you imagine racism, homophobia, sexism, etc should be justified if the targets are criminals?
And even if you do believe that, there's the problem of disproportional treatment. Why should trans criminals face more intense (and extra-legal) punishments than cis people committing the same crime?
And finally, the transphobic journalism is a problem because it obscures the facts and makes it unclear what exactly is happening. How can we even judge if unfair treatment is justified if we can't trust the reporter to be accurate about very basic facts of the case.
