Why do the other characters in olivia's household hate malvolio

Olivia's household hate Malvolio because he is a puritan. AKA a guy who doesn't have any fun and expects the same from his fellow servants. He is a party pooper- no music, no dancing, no acting no fun. In the Elizabethan times people would have hated this! This is why Olivia's household hate him. 

Of course, this was all a prejudice but from how Malvolio (Puritan) was treated we can see Shakespeare also disliked Puritans. This could be because Puritans thought enjoying theatre was also unallowed(a sin) and of course Shakespeare would disagree since he wrote plays for theatres.
 

Well, in the music industry during the 80s  cyndi lauper took a risk in changing a certain type of music art into something creative with her hair dye and wild hairstyles that were bold, her style was entice and screeching that she actually did her get a lot of hate for it because at that time hair dye and crazy patterns wasn't the norm girl's just wanna have fun for example that changed the work of her genre and a lot of people were influenced by her ways. there was other people who took the dare but not a lot. that itself refers to change in art style, because modern times changed.
