You're right! From wikipedia:
The Romani, also spelled Romany or Rromani, colloquially known as the Roma, are an ethnic group of Indo-Aryan origin who traditionally lived a nomadic, itinerant lifestyle. Linguistic and genetic evidence suggests that the Romani originated in the Indian subcontinent; in particular, the region of present-day Rajasthan.
As you can see, lots of people don't read those explanations.
Perhaps clearer communication would be beneficial.
