It is easy to judge as your brain likes to believe “your way” is the right way. So, you and your experiences become the measuring stick for interpreting other people’s actions.
The scary thing is this can easily let you slide into being righteous and stereotyping.
So, before you respond to a situation ask yourself:
Am I reacting because what was done goes against my values?
What facts do I NOT know but I should know before I jump to conclusions?
Are there any assumptions I am making?
Then, step back and see if you can remove the judgement to gather the facts and look at the situation from a pure angle.
