(the following statement is meant to be sarcastic)
What a horrible organization this Foundation is. Why just read their mission statement:
We Are Family Foundation celebrates our common humanity and the vision of a global family by creating and supporting programs that inspire and educate individuals of all ages about diversity, understanding, respect and multiculturalism; and to support those who are victims of intolerance.
The only mention of "sexual identity" is in the tolerance pledge. And then the entire statement is:
To help keep diversity a wellspring of strength and make America a better place for all, I pledge to have respect for people whose abilities, beliefs, culture, race, sexual identity or other characteristics are different from my own.
The choice is up to you. Personally, I no longer believe in the good intentions of our public schools.

Check this out from the authors of the "Tolerance Pledge" (a link to which is included on the page you reference)...

Oh, BTW "LGBT" Stands for Lesbuan, Gay, Bisexual, Transgender.
No, there's no agenda here... (/sarcasm)
