Narcissists like these should learn to control their emotions and that not everybody they conceive as intolerant is perpetrating „violence“. Real tolerance means that you have to accept that some people say something you deem to be rude or „unethical“.
When some asshole constantly refers to me, a man, as „she“ and I find this offensive, then I stop talking to that person. It’s as simple as that. Why do these whiny brats insist on being referred to by their ridiculous made up pronouns?
There are two biological genders/sexes with certain characteristics and behavioral tendencies. Everything between are just variations. We use words to describe reality as it is not how we want it to be. And we don’t need a word for every concrete entity. In fact we use categories like „male“ and „female“ to economise our perceptions of concrete things which largely share the same attributes (like that men only have penises) to enable us to navigate through the world (conceptualization).
If a specific entity (like a person) is to be addressed then we’ve got names or designations. Short: made up pronouns are totally superfluous. It is just impractical and confusing.
Like Ayn Rand said:
Words are a lens to focus ones mind.
They shouldn’t be used to „un-focus“ it.
