I don't add trigger warnings to my stories. My stories deal with sensitive topics and as such I try to deal with them in a sensitive manner. They speak for themselves and aim to not add to any hurt, but neither do I claim to have the solution for any hurt that you, the reader might experience in your personal life. If you feel activated in a negative way by what you read, I can only urge you to be kind to yourself and seek out some professional help. 
I don't mind getting critical feedback however, especially in relation to the cultural and historical aspects of my stories. I do research before and while I write my stories but don't claim to always get it right. If you find I am of the mark educate me. Of course there is such a thing as poetic license but I would hope that my characters represent the facts and groups of people fairly, encouraging understanding rather than reinforcing stereotypes and prejudice, so I am always open to suggestions.
