I don't know much about LGBTQ parenting, but I need some sources to debate someone. Can you help me out?

Maybe this troll just pissed me off, or they’re being old-fashioned, but I was debating with someone who says children need a male and female figure in their life to grow up “normal” and have a good balance.

Obviously, I know this is not completely true, as there are many non-traditional parenting structures out there, but I don’t know where to start researching this.
