As there were some Jews in Central and Eastern Europe who were also gay or Communist or socialist or disabled or mentally ill, were such Jews counted among the Jewish victims or among such other victims?
I can't imagine that in Eastern Europe, Jewish victims came across members of groups like gays, Jehovah's Witnesses, socialists, etc. who would also have been transported to the camps?
Regarding your first question: Despite very good records, estimating the number of Jewish Holocaust victims is still, well, an estimation of about +- 1 million. So classifying Jewish individuals who were also, let's say mentally handicapped or gay doesn't really impact our figures.
Regarding Jews being Bolsheviks or communists, that's a bit trickier, as they were disproportionately involved in those movements and the number of Jewish victims aligned with those movements was undoubtedly in the hundreds of thousands, maybe even 1 million+. That said, if you consider the Nazi tenet of Judeo-Bolshevism - the "perception that Communism was a Jewish-inspired and Jewish-led movement seeking world domination from its origin," you understand these groups were almost indistinguishable from the Nazi perspective.
