From your Wikipedia article:
> Leading questions may often be answerable with a yes or no (though not all yes–no questions are leading).
And specifically referencing your example, still from your article:
> Leading questions are distinct from loaded questions, which are objectionable because they contain implicit assumptions[3] (such as "Have you stopped beating your wife?"
That is to say: the question posed is not a leading question, and the article you linked as a citation in fact directly refutes your specific example.
Your article helpfully informs us that your example is a “loaded question,” and we can ask Wikipedia what distinguishes such a question:
> A loaded question is a form of complex question that contains a controversial assumption (e.g., a presumption of guilt).
https://en.m.wikipedia.org/wiki/Loaded_question
Yet the original question still fails this new test: there is no controversial assumption, and certainly no presumption of guilt.
Unless, of course, you think it preposterous that anyone would hold a belief such as “queer people should be beaten to death for their sexual orientation.” Or that it’s unlikely or even impossible that one’s coworkers would hold such a belief.
Unfortunately, neither of those are exceedingly controversial - it is trivial to find ample evidence of outright calls for the execution of LGBT individuals in the past month, and I leave that as an exercise to the reader.
The most controversial assumption here is that such a person might be a coworker. And frankly, that just doesn’t rise to the level of a “loaded question.”
You just didn’t want to answer.
