Bisexual, Pansexuals, and queer folk still can biologically produce children. Plenty of non straight folk making babies. Along with plenty of heterosexual straight biological women being artificially inseminated due to reproductive health issues with the biological male or biological female in the relationship. Biological Male/Male gay couples often have a biological woman be a surrogate. While biological female/female gay couples find a sperm donor. You are welcome to be proud and straight and mush as someone to be proud to be gay, but straight people are not the only option for human life.
