I am a pole, brainlet. While their language isn't directly purely slavic and their phenotype specific to a pre-slavic migration, doesn't change that they are culturally and politically part of the slavic bunch which inhabits the baltic area. If you want to be autistic, we can list all people which live on the baltic sea, and all of them, inclusing the finns and swedes are at least partially slavic (the horror for, at least for germaniskis), let alonge the russians, esthonians and latvians.
Baltic slavs are a thing and now go away.
