If someone calls me something offensive (lolmegettingoffended) then I just brush it off. The key to not be offended is all about perception and to understand that the way people react is based on their life experiences.
In most cases, when people attempt to be offensive, it's not really aimed dead at us. It often has to do with how they relate to the topic.
We're all just living in the projections of each other's life understandings and often we are just the proxies, the chess pieces of life to which our loved ones have their own built-in reactions. I'm not saying this to automate life or omit the familiarity from our relationships, but mainly for us to know that almost every time we get vexed, we are actually just in a misunderstanding.
And if it wasn't us, then it would definitely be someone else tbh.
I say just live your life full of contentment, irrelevant to what other people say, think, and do.
