Just because there has been a rise in crime that doesn’t make the right wing horror stories any less false. Saying “crime (mainly property crime) has risen a bit* in San Francisco, and there is a serious homelessness problem” is not the same thing as “liberal policing policies have resulted in a dystopian anarchy and you shouldn’t go anywhere near the city or you’ll get murdered the moment you set foot in it”.
San Francisco is a amazing beautiful city, that has some issues. If the OPer believes the horror stories and doesn’t visit, it would be a huge shame.
* - also I was in SF during that crime rise and a lot of it was caused by the SFPD basically going on strike and refusing to enforce laws because they disagreed with policies like Prop 47. Apparently this got worse when SF appointed a liberal DA, and the police just refused to do there job at all, though I had left by then.
