You are very correct, but it depends on what your country has received. My country for example received millions of Romanians/Bulgarians back in the day, so that's what people were against. There was a huge construction bubble, and they came en masse, leaving many locals without a job. As soon as the construction bubble popped, they left en masse. They also greatly increased the insecurity here, with really recurrent news about thefts committed by Romanians, pickpockets, etc. News were flooded with those events. So, you can imagine what the locals ended up thinking of them. Natives wouldn't say anything negative about rest of slavs, Poles, etc because they simply never met them.
