What are your thoughts about parents that throw their kids out of the house because they admit that they are gay or lesbian?

Watching the news this morning and they covered a fund raiser for kids that have been kicked out of their homes by their parents for admitting they were gay or lesbian. Gina Gershon was the host but I can’t remember the name of the sponsor. How the hell can a parent turn on their kids for this? It doesn’t change anything in my mind, but it’s enough for you to throw them out on the street? What are your thought? And why do we distinguish between gay and lesbian?
