Wrong. That is one particular prejudice that comes under the category of sexism.
Wikipedia defines sexism as below:
Sexism is commonly considered to be discrimination and/or hatred towards people based on their sex rather than their individual merits, but can also refer to any and all systemic differentiations based on the sex of the individuals. |
Sexism can refer to subtly different beliefs or attitudes: the belief that one gender or sex is inferior to or more valuable than the other (male and female chauvinism); hatred or distrust towards the opposite or same sex as a whole (misogyny and misandry); imposing stereotypes of masculinity on males or femininity on females.
