The Gas

When the Nazis were gassing the Jews in WWII, there were some others thrown into the oven.  Priests and nuns, Roma called gypsies, and another group, homosexuals.  If you were a homosexual, be it a blue-eyed, blond hair German, you got the gas.  Ever since the war many people have defended and supported Judaism and worked against anti-semitism discrimination.  So why are many of these same people so upset about any decisions that try and erase discrimination against the homosexual?  Ponder that one.
