Like my fight or flight meter skyrockets and I feel like I’m in danger.

You should feel afraid, it’s a normal reaction.

People yelling and getting into loud arguments in public with others around is a sure sign that they are socially unaware or ignorant and find it completely normal to raise their voice in argument with strangers and in public. It means their social norms involve not caring about making others uncomfortable and in not minding letting others see how dysfunctional their lives are.

I’m always afraid of people like this because if they don’t mind yelling or having loud arguments with those close to them while others are around … it often means that you can land in the line of fire at one point.
