Only homosexuals of certain political or racial bents were in the camps. Homos built the early Nazi movement and were quite welcome until they became politically inexpedient to associate with and when Hitler was taking steps to hide his own early period within that cult.
That is quite true. The Nazis were extremely tolerant of homosexuality (and all sexual deviancy, for that matter). Few, if any, homosexuals were interred in camps exclusively because of their sexual preference.
