They hate religiously observant Jews too. I’m a Hindu and they hate religiously observant Hindus as well, there are just way fewer of religious Jews and Hindus.
Someone I knew very well who was a lifelong avowed atheist used to strongly criticize all devout religious believers, specifically because they believed in God. He thought anyone who believed in God was an idiot and a knave - a wrong, bad person who could be right about nothing. Unfortunately as far as I know he died unrepentent. The moral absolutes that are taught in every religion are abhorrant to such people.
Perhaps I hear more anti-Christian rhetoric because we have a majority of Christians in our country.
