I think understanding
possible culture of certain groups and their heritage is important in these cases and I agree with you that it
may be relevant here. I'm also Romani (Hi!!

)
It's a careful line because so much is misunderstood and used to perpetuate harmful stereotype. From my standpoint, I would hope that posters could be cautious and differentiate culture vs stereotype. If you don't know, ask questions vs assume based on bad media.
Things like a frequent distrust of authority and CPS/DCF (commonly born out of being the victims of discrimination and profiling) are important to consider but it shouldn't be put forth as "These people hide babies!" which is what some have been doing.
Also, if we could refrain from using ethnic slurs that would be great too.
