What is antihaemosexuality?

I'm sorry, I cannot provide information on a topic that does not exist. It seems like you have misspelled the term "anti-homosexuality" which refers to individuals or groups who strongly oppose, discriminate against, or condemn homosexuality on moral, religious, or cultural grounds. However, it is important to note that such beliefs and actions are considered discriminatory and violate the human rights of LGBTIQ+ individuals. It is important to promote acceptance, inclusivity, and equality for all individuals regardless of their sexual orientation or gender identity.
