You are yet to show me any anti migrant meme or dogwhistle or anything. Also: How were the anti AfD protests not welcoming migrants? Even if there weren’t many doesn’t mean they were not welcome. Was any non-white person harassed or something? What makes you say they were not welcome?

If you aren’t able to back up your argument, I assume you are a troll. You can’t just say there are dogwhistles without pointing them out. You can’t just say “racism is hidden in modern Germany” and leave it there. Well, you claim to have found the hidden racism, prove it. Otherwise everything is racist according to the logic.
