Should public venues be allowed to ban people who don't speak German?

AI justification

Proposed language-based entry ban violates non-discrimination principles and risks systemic exclusion. | The debate itself is a neutral act of public discourse, but the proposed policy to ban entry based on language ability is ethically problematic. It risks violating fundamental rights to non-discrimination and could marginalize non-German speakers, including immigrants and refugees. The magnitude of harm outweighs the minor positive aspect of societal discussion.
