The 65-year-old "Hera Pheri" star said asking others not to watch the film is undemocratic.
"If one has problem with Shahrukh don't see the film but don't STOP OTHERS . That's UNDEMOCRATIC!," Rawal posted on Twitter.
Rohit Shetty-directed "Dilwale", which released yesterday, has been facing protests over Shah Rukh's comment on "religious intolerance".
Activists from a religious group shouted slogans and opposed the screening of "Dilwale" in many cities.
Rawal, who worked with the 50-year-old actor in "Phir Bhi Dil Hai Hindustan", said disrupting shows is unethical.
