I'm suspecting that is only because of behaviors learned from US on the internet. If not for that they wouldn't have thought of banning for it. It's not a topic that comes up often, but IRL negative views on gypsies are the norm in Europe.
I think it's important to understand that it's viewed as culture issue, not color-of-skin issue (that is something that can be changed, people of gypsy heritage that go to school and work are not considered gypsies for this) and so not getting filled in the category of "racism".
Now we could have a discussion on whether being poor is a choice or a consequence of societal inequality, but I think more people agree on racism here...
I said the exact same thing for like 20 years. Until I realized that this thought is utterly racist. Luckily, I was disgusted about myself and my environment where this is a normal thought, and improved, instead of doubling down.
You've just called a behavior based on a name of an ethnic group. You cannot be more racist than that.
Most often it is the mainstream society living in stationary houses describing people living in temporary encampments with a different culture.
