I don't disagree with the spirit of your comment, but you have to draw the line at some point. Regarding marriage, in Spain it's like in Germany, you can marry at 16 with the explicit permission of a court. I don't really agree with that (it makes no sense to me that people who are not considered mature enough to drink or drive can marry) and anyway I doubt courts would authorize arranged marriages, but let's set that aside, and focus on "around 2% of Roma girls aged 10–15 are married". 16+ is debatable, but surely we can agree that marrying before 16 is not okay? And 2% is of course a minority, but far from rare (in Spain we would be talking about something in the order of hundreds of such marriages per year). Regarding hospitals, of course it's not a problem of huge importance, but it's an example of how clashes can occur in everyday life and can cause laypeople to reject these cultures. In Spain, each public hospital room typically houses two patients. Being there with a sickness that calls for peace and silence and having 20+ people packed in the room or crowding the corridor to be with your roommate is not a pleasant experience, and this is rather common (as in, I know several people who have experienced it). Limitations on visits are not a specific law, they are just hospital policies for capacity and operativity reasons, which are even more limiting in cases like ICUs or during the COVID-19 pandemic. Also, they affect everyone. It can happen for example that a parent of five dies, and not all of their children can be with them at the moment of death. This is frustrating for some people, but it's how it works. So while I can understand that integration takes some effort by the majority population, what do we do? Allow 30 people to visit for a given collective but people not from that collective could still be denied being in their parent's deathbed? Allow it for everyone, which would need an exaggerated amount of resources? I see no reasonable solution other than just enforcing the rules, to be honest.
