I believe it can be true. And it could be not a coincidence that the area near Poland/Ukraine boarder is marked as LGBT-free[0]. I think the situation should be better in the capital Warsaw or Vilnius(Lithuania). I feel shame for those racists.
On the other hand it can be popular kind of propaganda: "And you are lynching black people"[1].
