Another way of saying this is that Lithuania is currently either culturally or politically suppressing trans people, whether inherently or knowingly - I promise you trans people and their alternative identification exist there, too. You just dont see it and/or they are afraid to say so.
In those countries there are more important issues to protest about, like what is happening in Belarus, and unfortunately is something that doesn't have the same news impact as the BLM protests.
Is Malgorzata Szutowicz an Eastern European who thinks about "sex" and "gender" as different concepts?
I quoted a BLM protesters as saying they were there "to show solidarity but also to point out the problem of racism and police violence in their own countries", which includes racism against the Roma people.
People in other countries is worried because every time a problem is framed under anglo-narrative constraints it becomes distorted, unnecessarily confrontational, and it distracts media from talking about the real problems people care about.
BLM protests in particular were weird in many places. In my city there was a bunch of people (mostly whites) and it wasn't very well received, because there were other very pressing issues (like people dying by the thousands by a virus).
You find some articles via google search about things like "black lives matter" in Croatia and claim it is relevant there somehow. There was a BLM protest in Lithuania too (where I am from). There were maybe 10 black people in that protest. Half of them when interviewed said they were traveling through different countries (Estonia, Lithuania, Poland) to create and initiate those protest. Then if you look at the people who attended - mostly teenagers. When asked why they are attending this protest they came up with "to show solidarity for US". Which is to say - they are being fed US politics over the internet and found an opportunity to join an event here.
So that's how I see it. These US political things leak to other countries. Through media, through twitter and instagram, and now even through HN.
