“One doesn’t need to make things unnecessarily complicated at the outset. He who raises his right arm at a slant forcefully and repeatedly while standing on a political stage at a political speech in front of a partially extreme right public is performing the Hitler salute. There is no need for ‘allegedly’ or 'similar’ or 'debated’. The gesture speak for itself, it is documented on video. Whoever then wants to reinterpret it, whoever doesn’t want to see (i.e., refuses to recognize) the Hitler salute, does so on their own behalf.”
(sorry I am really bad at translating but this is roughly what it says, for my non-German speaking mutuals)
