Homophobia is when people don't like, accept, or feel comfortable around people who are LGBTQIA+; so they might make fun of them, make them feel bad, or even be mean or hurt them.
In ethnic minority communities, some people might not like LGBTQIA+ people because of their religion, beliefs, or culture, and they might pass this way of thinking down to their family, friends, and children; so they might be taught to be homophobic. This can make it harder for LGBTQIA+ people, especially if they feel like they can't be accepted in their own communities. It's important to remember that everyone deserves to be respected and accepted for who they are, no matter what their background is.
