I agree that Mc is made up bullshit
Boy do I have bad news for you about every other word that exists in every single language. There is no word tree we harvest fresh ripe new words from, everything is made up. We are just meat squirting air through our various holes because we like the sounds they make and wish to communicate thought.
Something being made up doesn’t make it bullshit, but something made up by a tiny minority within a minority expecting everyone else to adopt it certainly does.
Is it really so hard to respect a person enough to address them with the courtesy title they ask you to use? Are you in any way inconvenienced by saying “Hello Mx. TWeaK, how are you today”?
No, but unless someone tells me that they want to be referred to as “Mx” I shouldn’t be expected to assume that. Furthermore, when they tell me and my natural response is “Huh?” I shouldn’t be vilified for not knowing what they mean - neither should they be vilified for coming up with a personal definition that suits them better.
It’s a two way street. You’re free to be yourself and to stand out from the crowd, but doing so naturally invites inquesition. Such inquesition is not inherently malicious, even if malicious people are more likely to ask questions.
The reasonable ground is somewhere in between. Noisy people on either side demand that they be seen as right, but the fact is they’re both an insignificant minority with an unobjective opinion. One minority is smaller and more vulnerable, and that should be taken into consideration, but that doesn’t mean everything they say is right.
