You know the proverb about Nazis: You are either a good person and smart, then you cannot be a Nazi, or you can be smart and a Nazi, then you cannot be a good person, or a good person and a Nazi, then cannot be smart.

If you vote for the AfD, you know full well what ideology they stand for. Very best case, you are tacitely supportive, but more likely to be firmly in the AfD camp. Or just manipulated, and that's why propaganda is the right word to use.

And yes, a ton of the anti-renewables / pro-nuclear talking points in Germany are actually just that: right wing propaganda.
