Yup. Some people are just evil.
It's also really insulting for those with mental unwellness. Being mentally ill doesn't make one a bigot, nor should someone's bigoted actions be given a pass if they do have a mental illness.
Being a fucking bigot makes one a bigot.
People using mental illness as a 'get-out-of-bigotry' card irritate the fuck out of me. No.
Don't be a bigot.
