Statements like 'twitter is full of transwomen holding knives' are uncritically accepted here as true
As I wrote above, a while back among trans people and trans activists on twitter there was a popular meme called "POV ur a terf in my mentions". This is some of the stuff that was all over the place:

The point of the photos was that some trans people and trans activists were so upset whenever they saw a tweet that they viewed as being by a "TERF", ie a woman, they wanted to send a message. The message was to show what the woman would see if the person who posted the photo was able to confront them in the real world, that is the woman would see the person using a weapon to intimidate them or would see the person attacking them with the weapon. The photos in that link are the tip of an iceberg.
It really doesn't help the trans cause to pretend stuff like this doesn't exist or isn't common. Doing this protects misogynists who threaten violence to intimidate women.
However, it's one thing to be in denial to maintain your own world view but it's not right to prevent others from seeing what actually goes up on social media. I don't think MNHQ should cooperate in this by brushing this stuff under the carpet.
