Some people want non-normatives to get back in the institutions and out of sight where they belong. Some people don't want governments to pay for accommodations or in some countries, disability payments. Some people want to erode legislation protecting the disabled in the workplace (through stigmatising the perceived recipients) or to narrow the group that applies to (you're not really disabled!) Some people want it to be cool to bully disabled people and find that (compassionate) recognition of disability increases public sympathy.
