Unfortunately all too true. The same Nazi's were seen as a minor league joke by the German Left and Centre and described as mindless uneducated thugs. Until they were no longer a joke.
You just need a mantra.
"We need to do something, our country is under attack by (insert ethnic group of your (dis)liking here)! The country is in tatters and only we know how to fix it! Vote for us and we'll have this mess sorted pronto! And we'll get rid of a few people we don't like along the way"
No actual fixes are presented, other than blaming migrants or minority group.
This is nothing but a cynical ploy to garner votes.
I never said the right wing parties where stupid, it's more the right wing voters that are the problem, because they keep bying the same snakeoil and utter Horsescutter over and over again.
If you just stand before a group of people, puff yourself up and address the them in a loud, authoratiarian voice, oozing self-confience and keep repeating the above mantra over and over again, you WILL get votes.
People don't like to think for themselves. They just want someone to stand in front of them and deliver easy answers and scapegoats.
People keep falling for this sh*t over and over again. It's not just stupidity, it's (by definition) madness.
