Discrimination is pervasive, frequently open and unsanctioned, and includes discrimination, both direct and indirect, provided for by legislation. While all commonly disadvantaged groups suffer it, some communities are particularly gravely affected, including Roma, people with disabilities, especially people with mental difficulties,LGBT (Lesbian, Gay, Bisexual, Transsexual) people who face open hatred when expressing themselves openly, ethnic Macedonians whose existence as such in Bulgaria is simply denied, and racial minority immigrants who are brutalised and shunned.
