If you want the short answer, yes, even using the upright version, people will probably take offense or assume you're trying to "get away" with using the Nazi one without technically using it. Chances are, Ubi will side with the people who are offended with it. It's unfortunate that one group had to ruin things for decades to come like that, but as you're posting this ahead of using it, I suspect you understand.
