The blue line flag used to be to honor the police force. It's being used now to support police's racist decisions. Fucking extreme republicans hijacked the blue line flag, then slapped it on the American flag. This was before they became MAGA republicans somehow hijacked the American flag. No hate on sane republicans, though. You're cool!
Yikes. I am completely democratic, but there are some republicans who can think straight and aren't MAGA racists. And while most cops are probably racist, and the entire system was built on slave catching grounds, there are still the occasional no-hate police officers. While it is still better safe than sorry, you can't assume the worst of every policeman and Republican.
