It's a fairly conservative Christian organization. In 2001, they argued they (and other religious groups) should be exempt from anti-discrimination legislation (which was denied). In October 2001, the "Salvation Army Western Territory" began recognizing same sex domestic partnerships for benefits for their employees which was pretty universally shit on by most Evangelical and other more radical Christian groups and was rescinded by the national Salvation Army in November of the same year. They've done some other stuff in the UK and New Zealand pretty strongly opposing same-sex marriage and relationships. In 2013 it came out [hehe] that they were referring LGBT people to conversion therapy [from what I understand, it was on their website and it was taken off after the news broke].

tl:dr They've had a history of being assholes to the LGBT community and they haven't done much at all to get better.
