According to some studies, the members of the LGBTTIQ community are accepted by the majority of the population in Germany. But many LGBTIQ individuals still experience hostility and discrimination when they "come out". According to the law, you can take legal actions against the offenders: If someone harasses you or discriminate against you because of your sexual orientation or sexual identity, you can contact the Anti-discrimination Agency. In Germany, there is an anti-discrimination law known as the "General Equal Treatment Act" ("Allgemeines Gleichbehandlungsgesetz") which protects individuals against discriminations they may face because of their skin colour, country of origin, sex, religion, disability, age or sexual orientation/sexual identity. If you are mistreated or discriminated against during job-seeking, at work or in a restaurant, club, shopping centre, bank, or during flat-hunting, you can contact the Anti-discrimination Agency ("Antidiskriminierungsstelle"). They will check the case, see if you can take legal actions against the perpetrator and further advise you about your options.
You can reach the Anti-discrimination Agency on Mondays (13-15 o'clock) and Wednesdays and Fridays (9-12 o'clock) at 030-185551855 or write to firstname.lastname@example.org. Their staff speak German, English and Arabic. You can also search for one of the counselling centres of the Anti-discrimination Agency in your area.
Please note: If you face verbal, physical or sexual assault, you can always call the police at 110.
