Lead With Love is a 35-minute documentary created to help answer that question. It is free to watch at their web site. Below is a short trailer.
This is an excellent, informative film
that everyone needs to watch, not just parents of LGBTQ kids. The film promises to have a profound effect on those that watch it, regardless of your sexuality or beliefs. As far as I'm concerned, it should be aavailable in schools, places of worship, and any other place that parents gather. It will change you for the better...LEAD! (watch the film for what that stands for.)
