I second billy's comments. Why do you care about these insignificant things? I've never even heard of these people and don't care. You must really look hard to find these things. Why don't you worry about something more important? You really need to get a full life, instead of just a half life.
Seriously, why not do something positive that wil help others? I can almost guarantee that you will be a happier person if you stop worrying about what others do in their private lives, and instead put your energy into something better.
Because these people are trying to force us to use their preferred pronouns. It's a form of fascism. If we don't want to use their pronouns, we could face harassment charges. It's not right that we have to feed into people's delusions in order to placate to them. You guys claim you are big on science. Well, science says there are only 2 genders, not 5,672 genders like facebook and the left says there are. Those are FEELINGS, not FACTS!
You guys are supposed to be the science guys! We don't give in to schizophrenics, do we? We get them mental help. No one says, "Yes! I do see the invisible walrus you are ranting about!" This would be encouraging them, not helping them.
Why is it wrong to want to HELP people instead of coddle them? Do you people WANT fascism?
Nobody's forcing you, or even trying to force you, to do anything.
They are simply asking politely that you refrain from being a rude prick.
If someone's birth certificate says their name is William, but they introduce themselves as Bill, and all their friends call them Bill, and they ask you to call them Bill, then to insist on calling that person William is just being a rude prick. It's needlessly assholish behaviour. You are effectively saying that their preferences are overruled by an arbitrary and impotent document, that they never agreed to. Why would you do that? Is your version of The Truth more important than the feelings of others? If so, fair enough - you're just an arsehole. As we all are, sometimes.
There's nobody and nothing that will FORCE you to stop calling that person William. But it's reasonable for people to warn you that doing so will mark you out to others as an arsehole.
This is what's happening with gender identity. You are being a pedantic arsehole, and people are calling you on your impolite behaviour.
Of course, as you (like everyone) have a self-image as a noble, moral, and upstanding person who is the paragon of kindness, honesty, and grace, being called out as a rude arsehole feels like an unprovoked attack. But it's really not. Nobody's forcing you to do anything. But if you don't want people to think of you as a rude, mean, or even cruel person, you are going the wrong way about it. That doesn't force you to change your ways. But it might mean that you will mske yourself feel uncomfortable if you don't. It's entirely your choice, either way - the world doesn't owe you the right to feel good about yourself when you are needlessly cruel to others.
Most people over the age of ten are able to spot the difference between being told that they are being rude, and being forced to do something. If the penalty for not complying with someone's suggestions or recommendations is merely that you will feel bad about yourself, then they aren't forcing you to comply.
