The fact Europeans are so open about hating gypsies is hilarious, like I legit saw one saying "its fine because they are like if all the stereotypes of american blacks were real" (implying those stereotypes arent real too). They will be open on how they hate gypsies because of rape and theft, but wont say the same about muslins and blacks without being crucified for it.
Its because theyve been around for hundreds of years? Does that mean that if blacks were around europe for longer, today you could just say the n word on european sub reddits and even them would be like "yeah they suck"?
I think there's a bias in the sample you're asking. Even in the soviet era when these countries were the toughest on gypsy crime (an actual legal term in afaik multiple countries, including Hungary [cigánybűnözés]) it was like uwu, not all gwipsies, only the bad ones stealing copper

. It's always been an extremely delicate topic for most urbanites, politicians. This was a time when the national police had actual dedicated gypsy taskforces (not manned by gypsies but dealing with crime related to them)
The word 'gypsy' is literally banned on most country-subreddits as it is deemed a slur now, the politically correct term is 'roma'. It's not even just subreddit mod cuckery, the admins will ban you for it, even if you say it in your own language. Not only that, but you'd get downvoted to oblivion because the average ledditor denies the existence of discrepancy in the rate of crimes committed by various minorities. We're all just pink inside, they just happen to be poorer for artificial, completely unfair reasons and all crime is solely to sustain themselves because the system has failed them and there's no other way for them to stay alive other than to steal two apples a day.
The people living in the countryside who have had actual, direct contact with gipsies in the form of neighbors, or being victims of violence, large scale theft of produce, animals, tools, whatever, have always despised gipsies, however. These aren't the people going on r/europe/. Coupled with the all-consuming feeling of helplessness- if you are an American, you genuinely have no idea. I reckon in your most cucked state with the worst self-defense laws, you are still better off than in about 98% of european countries. People truly have no idea how fucked up the legal system is in most places. Pedophilia, rape? Couple months in the clink. Violent robbery-murder? A few years and you're out. Theft? Fine or community work you won't do or pay because you're a gypsy. Tax fraud, which is the national sport of most central-eastern european countries? 20 years. You replace the wine on your farm that keeps getting stolen with antifreeze? You rig your fence up with electricity? You hit a gypsy on your property sneaking around with a spade? You're fucked buddy, you're 56 and you'll die in prison.
Most people probably hate the system more than they do shitskins. There's a reason according to a Policy Solutions survey made in 2018 54% of the people in this country would reinstate the death penalty (which will clearly never happen, especially not if you're an EU member), just for comparison in this same survey 79% of the population
supported 'free' abortions, which for example is a significantly more divisive topic in the US. We're a long way from cutting off thieves' arms.
