Can’t speak out against then speak out for, speak out and tell what is the best of German culture and why all should enjoy it. Speak out what is best and let the naysayers be reproached when they speak out negatively. Do the opposite of what they expect, be a Trump-et for good against evil.
That could be a problem also, speaking up for German culture.
Leitkultur, basically meaning the predominant Germanic culture. I remember Friedrich Merz, a former member of the CDU, he said that immigrants in Germany should adhere to “Leitkultur von Deutschland”.
This caused a big debate amongst Germans who want to return to Germany’s traditional Christian values.
The Left and the media went berserk. Merz was turned into a pariah and he retired from politics as a result.
