Here's my speculation: By getting really angry about it, you're acting in a way that would make the desirable belief (don't misgender trans people, for example) common sense. Most people would get angry if you openly state stuff like "Women shouldn't be allowed to drive cars because they're stupid." By getting angry about less accepted stuff, you (try to?) give your belief a more mainstream status.
The complication is that you can succeed at getting specific behaviors by showing anger.
Compassion and/or full inclusion in one's group is reflected by a much more complex and flexible set of behaviors, and I'm not sure anger is a useful tool for getting that.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
