@SeijoDani It's worth noting that the yellow labels are a political happening rather than an official sign (as the author explains on https://lgbtfreezones.pl).
The laws are real though, and it's about as sad as it is amusing to see the rationale for their passing – local goverments not even knowing what "LGBT" means: https://www.youtube.com/watch?v=cF_fQuoGq68 (Attempt at the video is “erm, lesbian-gays, bio-something”)
