They should make a campaign for tolerance of those with disabilities: "Stand up for those who can't"
I'm not sure what you meant, can you clarify?
They should make a campaign for tolerance for disabled people with that slogan. I'm joking. It's funny.
I can see the pun that you made with that slogan, but otherwise, I agree with you that we should try to help people with disabilities.  Nobody chooses to become disabled, but they have to live with their condition everyday, so we should support them and help them live their lives.
