A minefield? There wasn't a single mention of violence. Looks like they have to face the possibility of being rejected or referred to by pronouns they don't prefer.

I’ve personally had negative experiences on Grindr, too. I state in my bio that I identify as non-binary, but still receive a lot of messages starting with “Hey, man”.

Under U.K. law, this can be considered a hate incident.

When two in five non-binary people have experienced a hate crime or incident in the space of a year, these threats can feel very real.

Sounds horrific, right? This stat is only in the U.K., which loosely defines a "hate crime" as follows https://www.cps.gov.uk/crime-info/hate-crime :

"Any criminal offence which is perceived by the victim or any other person, to be motivated by hostility or prejudice, based on a person's disability or perceived disability; race or perceived race; or religion or perceived religion; or sexual orientation or perceived sexual orientation or transgender identity or perceived transgender identity."

So what separates a crime from any other crime is whether the victim believes the crime was motivated by hostility or prejudice based on a protected characteristic. But then we take a look at the source they linked, which actually says:

Two in five trans people (41 per cent) have experienced a hate crime or incident because of their gender identity in the last 12 months and one in six LGB people, who aren’t trans (16 per cent), have experienced a hate crime or incident due to their sexual orientation in the same period.

1. They are taking the number for all hate crimes or incidents (this is important, we'll come back to it) faced by all trans people and saying it's the number for non-binary. ALSO they claimed it was hate crimes, when the source actually references "hate crimes or incident". So what is a hate incident?

They say something is a hate incident if the victim or anyone else think it was motivated by hostility or prejudice based on a protected characteristic.

Hate incidents can take many forms. Here are examples of hate incidents:

verbal abuse like name-calling and offensive jokes
harassment
bullying or intimidation by children, adults, neighbours or strangers
physical attacks such as hitting, punching, pushing, spitting
threats of violence
hoax calls, abusive phone or text messages, hate mail
online abuse for example on Facebook or Twitter
displaying or circulating discriminatory literature or posters
harm or damage to things such as your home, pet, vehicle
graffiti
arson
throwing rubbish into a garden
malicious complaints for example over parking, smells or noise.

So when they claim "two in five nonbinary people have been the victim of a hate crime", what they really mean is:

In the U.K., two in five people who identify as transgender have read a mean tweet online.
