Final answer:
Heterosexism refers to bias and discrimination in favor of heterosexuality, while homophobia is an extreme aversion to LGBTQ+ people. Both contribute to the perpetuation of a heteronormative society.
Step-by-step explanation:
Heterosexism refers to attitudes, bias and discrimination in favor of heterosexuality. It involves rejecting or stigmatizing individuals who are not heterosexual. It is the belief that heterosexuality is the only acceptable sexual orientation. Homophobia, on the other hand, refers to an extreme or irrational aversion to LGBTQ+ people or those perceived to be LGBTQ+. Homophobia is often rooted in stereotypes and can lead to further discrimination against non-heterosexual individuals.
In a heteronormative society, heterosexuality is seen as the norm and other sexual orientations are marginalized or seen as deviant. Heterosexism and homophobia contribute to the perpetuation of this heteronormative culture. While there has been progress towards greater acceptance and understanding of different sexual orientations, these forms of discrimination still exist and negatively impact the lives of LGBTQ+ individuals.
