Nah, that's not exclusively an AfD thing. That's often boomer mentality. Many are out of touch with the rules for political correctness/decency nowadays and instead of trying to adapt, many try to make others stagnate as well.
The point of right wing politics is to enable oppressing groups that aren't 'pure' in order to profit. They will be selling each other "Climate Change Is Gay Propaganda" as their beach houses are flooded by rising oceans.
“There will be no curiosity, no enjoyment of the process of life. All competing pleasures will be destroyed. But always— do not forget this, Winston— always there will be the intoxication of power, constantly increasing and constantly growing subtler. Always, at every moment, there will be the thrill of victory, the sensation of trampling on an enemy who is helpless.
If you want a picture of the future, imagine a boot stamping on a human face— forever. ”
― George Orwell, 1984
