First, lemme just correct your grammar, which cements your approximate age as a 9-year-old: It's you're, I'm, and you're.
Second, I can apply that same logic to you. You're probably 9 or 10, thinking, "oh, lgbtq people are so bad, they like different genders from their own and may not identify with their birth gender!" but in the future you're going to be married to someone of your gender.
