One of the reasons why it was important for me to study microaggressions against lesbian, gay, bisexual, transgender, queer and questioning (LGBTQ) people was because I knew that this type of discrimination existed and because I hypothesized that they had a significant impact on the lives of LGBTQ people, particularly on their mental health and identity development. I collaborated with two fellow psychologist colleagues, Dr. Melissa Corpus, and we theorized the various types of microaggressions that affect LGBTQ people (see Nadal et al., 2010).
