There are a limited number of hate crimes against heterosexual people by homosexual people based on sexual orientation, but there have been a few instances. In heavily LGBT neighborhoods there have been some isolated cases of harassment against straight people.
Alternate use of the term:
"Heterophobia" has also been used by more conservative LGBT circles who are opposed to the traditional gay rights platform. They use the term to imply that extending equal rights to LGBT people is tantamount to discrimination against heterosexual people.
The term has been used by conservative circles who feel that when more liberal groups target them by calling them homophobic based on their positions that they can counter that liberal LGBT groups are being so called "heterophobic".
