What LGBTQ+ topic do you wish more people knew about? This could be a queer icon, a piece of history, knowledge about certain labels, specific philosophy topics (or notable philosopher), art, or anything else. Also if there are topics that you wish specific sub populations had greater access to or knowledge of, feel free to qualify (for example, you might wish there was greater knowledge about a specific cultural gender to all cultures which don’t have exposure to this gender, or a desire for your local gay community to be more educated on a topic important to you).
Or you could just check the magazine next time and avoid all the hassle. Jumping into in-group communications without even checking where or what they might be tends to go badly.
