I'm personally not offended by references to Nazism, but I do agree with Jaxvid that it is a knee-jerk turn-off for people. I try to be practical about things like this. Again, I'm personally not bothered by it, but others are.
I think the better way to engage people regarding "hard right" ideas is materials that they can read without feeling guilty or weird about. I think if every moderate conservative and Republican read the books listed below, and really absorb their ideas, it would really help a lot. And engaging them about the more "extreme stuff" (or what people perceive as being extreme) simply isn't necessary to confront the problems facing white people in the real world (immigration, economic woes, preferential treatment for non-whites, sports Caste System, etc.) and to come up with practical solutions.
