Since being shared, Mr Musk's tweets have become a target of a lot of criticism. NASA astronaut Scott Kelly wrote, "Elon, please don't mock and promote hate toward already marginalised and at-risk-of-violence members of the #LGBTQ+ community. They are real people with real feelings. Furthermore, Dr Fauci is a dedicated public servant whose sole motivation was saving lives."

Former CIA director and Barack Obama White House official John Brennan also voiced his concern with Mr Musk's tweet, saying, "Dr. Fauci is a national hero who will be remembered for generations to come for his innate goodness & many contributions to public health. Despite your business success, you will be remembered most for fueling public hate & divisions. You may have money, but you have no class."
Several internet users also criticised the new Twitter boss. "Cool, mine are Defund/Elon," wrote one user. "Your adjectives are sociopathic/moronic," said another.
A third user commented, "My pronouns are he/him. Because I refuse to mock people who are risking their safety and lives to openly live life on their terms. History will not be kind to those who were cruel and disrespectful to trans folks. And I hope I'm alive long enough to see and enjoy it." A fourth added, "Please sell @Twitter then delete your account."
