sigh.

It does not mean that if a person does a single thing thats considered a "red flag" they an evil abuser

It means they did something kinda sus

It means they made a bad choice

Or it means they did a dick move

They can even be having a bad day

The reason it's a red flag is because it could be part of a larger pattern of abusive behaviour

Could be does not equal Definitely Is

A red flag happens and you mentally take note and see how they react to being called on their bad behaviour and if they do more red flags

Everyone is "problematic" but we are also all growing individuals with the capacity to learn

You will have said and done things you aren't proud of in your life. That doesn't make you evil or bad because you did something once that is a "red flag"

Red flags and green flags are little indications of someone's behaviour. If a person ends up with more red flags then green and isn't willing or trying to better themselves... thats when you get concerned. Not when your friend has a bad day and snaps at you only to apologise later.
