Just a few things that you are apparently to ignorant to know or understand:
1. Being trans and being gay are two separate issues, although they my be related in ways that are clearly beyond your ability to comprehend.
2. Making assumptions about the sexuality of someone based on the position that they take on these issue makes you look even more stupid.
3. You can't count on any of your 8 kids to grow up to be as ignorant and hateful as you, as hard as I'm sure that you will try to mold them in your image.
4. It is likely that at lease one of those kids will be, in some way LGBT and you will have to deal with it
5. Most LGBT people were born of a heterosexual couple. There will always be gay and gender non conforming people,
6. LGBT people have kids. Some will also be LGBT but most will not be and all will be far more enlightened than you can ever be. Again there will always be gay and gender non conforming people.
7. Support for LGBT people is growing exponentially each year. YOU are already a minority and you are pitifully inconsequential.
