Cis men will really get upset when you, a non-man of any form, talk to them in the same kind of tone they often take with you.
Him: “Why do you get so defensive?” Me: “This is the tone of voice you talk to me in all the time when I ask you a question. Do you not like it?” Him: “I don't talk to you like this!” Me: “Yes, you do. All the time, actually. And it's not like I'm responding in an angry or whiny tone. I'm just adding to the conversation, which is what you tell me all the time when I tell you to stop being so defensive about everything.”
And then he goes on to pretend he doesn't.
Honestly, I wish more cis men would at least spend some time considering their speech and actions when people call them out on it. But that'd require reflecting on their behaviours, and I guess society would collapse if they spent even a fraction of a moment on recognising the ways in which their communication styles with other people create negative environments.
