Charities to avoid donating to this holiday season:
PETA: They'd rather spend money on publicity stunts than on the animals in their care. Last year, PETA killed 73.8% of the animals in their care.
FCKH8: A for-profit company that's widely uninformed, spreads misogyny, transphobia/cissexism, and bi/panphobia. They also steal their posts and designs without giving credit.
Autism Speaks: JESUS CHRIST AS A PERSON WITH ASPERGER'S I JUST WANT TO SAY, DO NOT DONATE TO THESE GUYS. They spend most of their money researching a "cure", support electroshock therapy on autistic kids (which has a +50% PTSD rate), spread stigma about autism, and don't have a single autistic person on their board.
Salvation Army: This is the most popular one to donate to during the Christmas season but please don't. They refuse to give this "salvation" to LGBT people, even kicking a homeless trans woman out for the sole reason of her being trans. They also refuse to hire gay people to their staff, for the sole reason of them being gay.
If you want to donate to a good charity, donate to Doctors Without Borders, The Gesundheit Institute, the Ronald McDonald House, or the ASPCA.
