International banking giant Société Générale is loaded with hate-spewing bigots in at least one of its Manhattan offices, where a boss routinely harassed and ridiculed a gay underling and superiors turned a blind eye to it, a new lawsuit charges. Mourad Raji said in a discrimination lawsuit filed in Manhattan federal court Wednesday that his 18 months as a sales analyst at the French bank’s Park Avenue office included being repeated referred to as a “P.D.,’’ a French slur for gay men, and that he was eventually marginalized because he is gay. Raji in the suit also claims that his ex-supervisor, co-defendant Thomas Jacquot, said “Salut [Hi] P.D.” to him 30 to 40 times and routinely mocked him by saying, “I don’t understand why you don’t have a girlfriend.” Jacquot was also routinely “hostile towards” other employees “who he perceived as being gay,” the suit claims.
