The BJP's response to Mallikarjun Kharge's letter to PM Modi was that the appointment of a regular CBI director cannot be done before the selection committee due to vacancies in the panel. This response is being called an example of intolerance because:

• It disregards the fact that the Supreme Court had directed the government to appoint a regular CBI director within a specific timeframe.
• It shows a lack of respect for opposition parties and their opinions.
• It highlights the government's tendency to sideline the opposition and go ahead with its own decision-making process without considering their inputs.
• It raises concerns about the politicization of key appointments and institutions, which may impact the functioning of the democracy as a whole.

Chidambaram's criticism of the response further indicates the opposition's frustration with the current regime's approach towards governance and decision making.
