Final answer:
Walter throws Mr. Lindner out of the house to assert his independence and maintain his dignity.
Step-by-step explanation:
In the play 'A Doll's House' by Henrik Ibsen, Walter throws Mr. Lindner out of the house to assert his independence and maintain his dignity. Mr. Lindner represents the oppressive societal norms and expectations that Walter rejects. By refusing Mr. Lindner's offer to buy their house at a lower price, Walter shows that he values his pride and self-respect more than the financial gain.
This act represents a significant moment of pride and defiance for Walter, as he stands up against racial segregation and the undermining of his family’s dreams and dignity. Rejecting Mr. Lindner's offer, Walter affirms his family's right to move into the house they have purchased and to resist the discrimination they face.
