The people who took care of me were genuinely of God. I suppose YMMV depending if you live in a sane country or not. We do live in the single most atheist country on the planet though, so I guess it's not globally representative...
I spent January and February of 2020 in a state park living in a two man summer tent that I had used twenty years prior and stowed away in the attic in the weird case I would ever become homeless. I was very proud of myself when I discovered that, good thinking. It didn't do much against the half meter snow, but I did get to see a beaver. Have you seen a beaver?
Underneath the thin facade of being a charitable organization, they're really a disgusting Protestant sect of Christianity who loath homosexuality and have a fair share of controversies. There's a few listed on Wikipedia if you want a starting point: https://en.m.wikipedia.org/wiki/The_Salvation_Army#Controversies
While they have acted shady pertaining to American labor legislation, they operate globally and they do not deny aid to those in need. There isn't a checklist of criteria you have to meet in order for the Salvation Army to help you.
I answered that elsewhere, so lemme just cut/paste:
Fair question: I saw they already had a partial spindle of mixed disks for sale. Just the one though, so I couldn't be sure it wasn't a fluke. Turns out it wasn't.
The spindles weren't the only thing I donated, just so we're clear. I just mixed them in with the rest of boxes of stuff, some of it pretty good. Someone can now snag an OG release copy of Bioshock 2 or Doom 3 for a song. Oh, and the entire Half Life Collection.
As a religious organisation, they are allowed to hire based on characteristics that you usually aren't allowed to discriminate with. They've repeatedly supported legislation that would allow them to refuse to hire LGBT people.
Across several countries, they've campaigned against the right for homosexual sex, marriages, inclusion in media.
They refused a $3.5m contract from the San Francisco city gov because it would've included giving the same domestic benefits to same-sex couples.
They said they'd leave New York if they were forced to offer the same domestic benefits to same-sex couples.
They campaigned against UK local councils including gay people in media like leaflets and the like.
High ups in The Salvation Army has said if you support gay rights you shouldn't donate to them.
They're extremely transphobic too, of course.
They did a bunch of child sexual abuse in Australia.
In the UK they own a lot of property that poor people stay in, and the conditions have been so bad that it was unlawful.
For the most part it's just that they're homophobic as fuck.
