The AfD goes beyond just opposing immigration and they struggle to shake their Nazi links. Talks of deporting immigrants, getting into minimising SS culpability for Nazi crimes, use of Nazi slogans, links to convicted Nazis and banned Nazi parties.
As a Jew there’s no difference to me between those who knowingly repeat Nazi slogans (i.e AfD) and “real” Nazis. It’s very easy to not be a Nazi, it’s unnecessary to make excuses for those who know what they are doing.
Germans (i.e. ethnic German citizens), should be held to a higher standard, because they are educated on this, there’s no excuse.
