Unless given country has similar % of foreigners (and of course they don't), you get where they come from and where the emotion 'foreigners bad' stems from. Even if one ignores flashy news about high profile attacks/criminality, which of course are impossible to ignore. Right or not, this statistics is primary level math that anybody can do in their head and even folks following populists will do.
Now what would you say to these people in such case? Bear in mind the topic is in western Europe, ie Germany so toxic that even saying above got high ranking people like police chiefs fired on spot. Exactly kind of dumb over-corrected setup that makes things like ADF thrive quietly, till election come and then folks are 'shocked' that they don't understand their own population at all.
