Brother if you offend someone, on purpose or by accident, if the person says, brother I am offended. You turn and say, I apologise, I didn't mean to. An apology is a symbol of mutual respect.
If you want to have a healthy and long term relationships with people, specially people of your race and culture, you would try your best to show respect towards them. that starts with language and vocabulary. Mutual respect is the best of understanding and cooperation. Please read my post, as soon as you told that Brother Troy is an entrepreneur, I said I apologise, that creates the space for a peaceful conversation. What did you on the first time you saw the love of your life, did you turn to her and said, Hey sister, you look like an a..le?
There is no way you can call a sister an B...ch or a...le. That's very disrespectful and rude.
I am aware that black people are trained to use terms such as B..ch, M.. er, Gangast, nigga etc, this is the programming that Europeans use in order to destroy our people's ability to be rational and emotional towards one another.
Please watch this and see what the sister is says, She is an University lecturer who lives in the US .
