If you do a Nazi salute - and this was a Nazi salute - without meaning to, and your response is not "oh **** I did a Nazi salute and that was totally not my intention", it really suggests you were either a) doing a Nazi salute or b) doing something so close to a Nazi salute (but ****ing it up and actually doing a Nazi salute) because you knew it would get libs and lefties and nearly the entire nation of Germany horrified you did a Nazi salute to get attention.
And having an arm temporarily in a certain position as part of a completely different arm movement is not doing a Nazi salute. Doing a Nazi salute is, however, doing a Nazi salute.
