1. Your people cannot say or write "God" and must instead write "G-d" to censor it.
2. Like a vampire, your people are offended by the crucifix and work to remove it from public places. Your people refuse to write the "+" sign because it resembles a cross too much.
3. Your people mutilate and molest babies.
4. Your people only eat abused animals and have inspectors to ensure animals are *properly* abused so that you can eat them.
5. Your people have secret underground lairs beneath DC and NYC.
Oh I think it is far darker than you put it. I imagine an underground lair that only the most evil villain in all history could have. Combined with infinite money.
I have no proof but I believe the tunnels are vast enough that they have transportation across the country or even multiple continents, and that their main purpose is to farm adrenochrome.
