Challenges of Using Correct Language for Different Cultures and Communities

I face challenges in writing with using the proper language sensitive to those of different culture groups. It seems like every group has a certain name they prefer over another, and it is hard to remember what each group prefers. For example, I thought that one should use homosexual rather than gay, but that isn’t right. Another challenge is remembering to ask the person I am interviewing what they prefer. Although there are rules for describing a certain person or group, sometimes the person or group prefers being described in another way. I need to be more sensitive and not just assume that I know the right way to describe something or someone.
