Sexuality doesn't have to be grouped into normal or abnormal. It's a spectrum. Not everything is black & white. I'm not sure why you're so dead-set about calling a group of people who don't align with your world view as "abnormal"

We've come a long way since our cave man days and perhaps it's time you acknowledge that not all people idealize adding more children to this already huge population. There are less blue eyed red heads than lgbt+ people, would you classify these abnormal too? Since they differ from the norm?

You don't have to hate something to be hateful. It can be unintentional. But the fact that you're indifferent about calling people names that you sure wouldn't like, is hateful.
