Based on the readings and what I've seen of this agenda, your characterization is inaccurate and an insult to millions or folks who were killed by nazis. Why is your use of propaganda any different than theirs? If you have a point to make, make it without watering down the historical perspective that comes along with the word.
If you want to study up on the relationship between Nazi Germany and homosexuality, read "The Pink Swastika" by Scott Lively and Kevin Abrams,
http://www.abidingtruth.com/ The website has the whole text available for reading so you don't have to pay a dime. When I use the phrase "homo Nazis" it is not propaganda, it is sedately descriptive. After you've read the book (it's only about 300pp) then post your rebuttal. There's no point in continuing a discussion until you've got some facts under your belt.
PS My husband is from Poland, his father was incarcerated in a Nazi slave camp for 5 years, his grandfather fought in the war, and has anecdotal evidence as well. FYI, around 6,000 homosexuals died in camps - they were not targeted for extermination, mostly they died of malnutrition and disease. The homosexuals incarcerated in camps were mostly "fems" (so-called effeminate homosexuals), who the ultra masculine Nazi homosexuals held in contempt, or they were innocent people who were labelled as homosexuals to get them out of the way (such as political prisoners.)
Read up on some facts before you get in the ring. You are speaking of that which you know nothing.
