The vaccine limit the spread of the disease, that's a fact. By how much is up to debate but it is not just effective at making the disease less severe. The wave of infections caused by the delta variant is faster, larger and deadlier in places with low vaccination rates. The vaccinated are less likely to test positive by about half, symptoms or not. Not perfect but the vaccine protects others. If the unvaccinated took the necessary precautions to avoid infecting others, it would be their problem (if healthcare is not overwhelmed...), but usually they don't. Just look at anti-vaccine protests, you don't see a lot of masks... And of course, if almost everyone in your area is vaccinated, most cases will be breakthrough cases.
