Every actor or supposed "star" seen smiling or applauding during this cheap stunt should be treated as a pariah by the American public until they're forced to leave the United States in shame. Fuck these people, openly celebrating a murdering KGB agent who we all know poisoned a journalist for criticizing him, amongst countless other crimes.
Damn them all.
UPDATE: We almost forgot to add the words of Glenn Reynolds:
Communists are as bad as Nazis, and their defenders and apologists are as bad as Nazis’ defenders, but far more common. When you meet them, show them no respect. They’re evil, stupid, and dishonest. They should not enjoy the consequences of their behavior.
