Why are Hindus only then allowed to speak about it when a Muslim says the same thing??

Ok. I'm not referring to only this subreddit. I've seen this in real life and on other parts of social media. Whenever a Hindu tries to say anything about Islam, other Hindus call them a Communal Bigot and Islamophobe. But whenever a Muslim says the same thing, everyone respects his opinion and lets him say whatever he wants to without saying anything. Why?
