> "Why do you think LGBT rights (first item on your list) is something that should be discussed at work? There are laws against discrimination and companies have to comply, but I don't see a good reason why this kind of topic should be addressed at the workplace."

In the United States, right now, trans people can literally be fired for being trans. The "laws against discrimination" that you refer to do not protect trans individuals, and those laws themselves the product of people organising together and deciding that certain kinds of discrimination should not be allowed.

That you included trans people in your example suggests you are currently unaware that laws against discrimination do not provide trans people the protections given to other groups.
