The Jehovah's Witnesses were only repressed as much as other draft dodgers. Or actually less, because a Polish German avoiding conscription would have his family endangered with reprisals, something which I know about intimately.

It was also only (some) gays, not homosexuals generally. And the purpose was to just reeducate them, at least as envisioned by the leadership (that they would be tortured by guards or other inmates wasn't planned). Also, they were exclusively German, and so for example one of leading French collaborationists was extremely openly gay and it didn't bother them (the Rohm Purge was political).
