Support Ukraine!

Take a stand against fascism!


PreviewQt stands in opposition to the unjust war waged by Russia on Ukraine, and condemns the rise of fascism, the extreme right, and Nazis in various parts of the world in recent months/years!

It is important that we learn our lessons form history and don't allow such big mistakes as in the past to be repeated. We all need to stand together to expose baseless propaganda anywhere we find it and oppose such fascist and racist tendencies wherever we are, be it in a smaller country like Austria or a big country like the USA. You can take part in this too:

  1. Consider donating to support humanitarian relief efforts in Ukraine. If you are considering donating something to PreviewQt, please donate it there instead.
  2. There are many protests and movements happening in many parts of the world to take a stand against all that is wrong with fascism and racism. Please find out what is happening where you are and join in!


Slava Ukraini     Say no to fascism and racism
