I know for men who are equal opportunity overexplainers it can still be seen as “mansplaining” when overexplaining to women.
But in general, if your tone of voice is right and it’s still happening, perhaps communicating your intention and a safeguard would work, at least sometimes?
May I try to explain this? If I start too basic, and overexplain so it feels condescending, please stop me so I can dig into it more technically.
