Every group has its members who dislike people who are different.  There are racists among people of colour as well as among caucasians.   LGBTQ people have their prejudices too.  I have been called a breeder by a gay person who I was arguing with, who was conveniently ignoring the children of her  LGBTQ friends.  

We need to try to understand and be respectful to people who are different from us, no matter where that difference comes from.  Telling me that I am a racist and implying that you are not does not help.  We likely both have biases towards people who are different.
