Its very well known that if somebody says something extreme, such as radical views, they tend to assume other people who dont oppose them, agree with them. The only possibility is to take your stance and give contra.
Also it‘s a difference to be against immigration versus the open salutation and worshipping of a mass murderer millions of europeans and americans have died for to stop.
For me it’s disgusting that this tabu is now broken and everybody still tries to loudly ignore it!
