No one wants to own a nazi bar.
Tweets by @IamRageSparkle: I was at a shitty crustpunk bar once getting an after-work beer. One of those shitholes where the bartenders clearly hate you. So the bartender and I were ignoring one another when someone sits next to me and he immediately says, "no. get out." And the dude next to me says, "hey i'm not doing anything, i'm a paying customer." and the bartender reaches under the counter for a bat or something and says, "out. now." and the dude leaves, kind of yelling. And he was dressed in a punk uniform, I noticed Anyway, I asked what that was about and the bartender was like, "you didn't see his vest but it was all nazi shit. Iron crosses and stuff. You get to recognize them." And i was like, ohok and he continues. "you have to nip it in the bud immediately. These guys come in and it's always a nice, polite one. And you serve them because you don't want to cause a scene. And then they become a regular and after awhile they bring a friend. And that dude is cool too. And then THEY bring friends and the friends bring friends and they stop being cool and then you realize, oh shit, this is a Nazi bar now. And it's too late because they're entrenched and if you try to kick them out, they cause a PROBLEM. So you have to shut them down. And i was like, 'oh damn.' and he said "yeah, you have to ignore their reasonable arguments because their end goal is to be terrible, awful people." And then he went back to ignoring me. But I haven't forgotten that at all.

I think about this post a lot
Tumblr post by stimmyabby Sometimes people use "respect" to mean "treating someone like a person" and sometimes they use "respect" to mean "treating someone like an authority" and sometimes people who are used to being treated like an authority say "if you won't respect me I won't respect you" and they mean "if you won't treat me like an authority I won't treat you like a person" and they think they're being fair but they aren't, and it's not okay. 642,270 notes

This picture was taken in 2000 by an Associated Press photographer who was allowed to be present as an observer. ICE now keeps press blocks away from the areas where they are operating. One of the first actions ICE takes during a raid is to confiscate phones.
A famous photograph taken in April 2000 during a federal raid in Miami connected to the custody and immigration case of a six-year-old Cuban boy whose situation had become an international political dispute between the United States and Cuba. The image shows armed federal agents entering a private home to seize the child, who is being held by a relative inside a closet.

Esto es flipante. Seis jueces y tres fiscales del Tribunal de la Haya que buscan juzgar a Netanyahu están sufriendo una persecución que ha eliminado su vida digital, convirtiendo su día a día en una pesadilla.

❤️ Love this ❤️

@mathforge.org has done what I’ve never been organised enough to do myself, and catalogued every #geometrypuzzle I’ve ever posted on social media. It looks amazing!

Ahir ens va deixar el Claudi Alsina.

Qui més qui menys coneix la seva tasca com a divulgador i com a professor de didàctica, però jo avui vull reivindicar el seu llegat de llibres de geometria escrits amb el Robert B. Nelsen. Són un tresor. Llegiu-los!

I love breaking the unspoken rule about fraction diagrams (all pieces congruent, not just equal in area). Here are a few of my favourite non-standard representations. A one radian sector fills half the unit square, the curves y = x² and y = √x enclose 1/3 of the square. Can you come up with more?
A one-radian sector of a unit circle filling exactly half the unit square. The curves y = x² and y = √x between x = 0 and x = 1 splitting the unit square into thirds. Two circles that perfectly fit side by side within a larger circle, each covering a quarter of the total area, leaving behind two 'batman' shapes which must, by symmetry, also cover 1/4 of the total area.
