When someone is a member of one of the most discriminated against and abused groups in society, public workplace announcements can be a very good thing, they show social support for the person, which discourages others from engaging in abuse and discrimination because sends the message that such abuse will not be accepted by the others.

What is the downside you see in this? Why are you so opposed to a good thing that you feel the need to speak out against it? How does this action, which helps someone else, effect or diminish your existence in any way?
