The majority is unaware of it. Being homosexual should not be a problem. Homosexuality in itself is not the problem. The environment, society, religion, bosses, colleagues and their values and prejudices too often are the problem. There are enormous differences in our positions in society and work in different countries and regions.
Harassment has many forms.
It is very depressing that gays face murder and death penalties in some countries. Or are put in prison. We are all normal people but in many countries treated as outcasts and freaks. Human rights are undermined, lives destroyed, personalities denied, qualities and talents wasted. Any society or company for that matter that discriminates and excludes homosexuals renders itself a bad service by wasting these qualities and talents.
