If what you meant by that is there would be less child birthing... There's so many orphans, there's surrogacy, and alot more heterosexual couples in the world versus lgbtq+ couples. And bisexuals can also have kids. Lesbians, if they choose to do so, can also have kids of their own.
So no, I don't think having accepting moms or parents will reduce the human population. But I think it will cause less suffering, specially among teens.
Why do people act like accepting lgbtq+ people means erasing straight people....? Y'all realize none of them would be affected right? They'd still exist and probably continue to dominate? We'd just you know have less people maybe killing lgbtq for existing but sure I guess equality would end humanity
How healthy the world could be if every mum are like this.
