Jurors heard Alice Cutter, 22, also complained about a colleague with Down’s syndrome being given a promotion ahead of her at work.
Cutter, from Halifax, is accused of making a string of offensive comments in a series of online chats with members of far-right extremist group National Action.
Cutter, along with partner Mark Jones, 24, also from Halifax, Garry Jack, 23, and Connor Scothern, 18, deny being members of a proscribed organisation.
Prosecutor Barnaby Jameson QC said Cutter posted messages in a group called “Triple K Mafia”.
“They will never be normal and it’s a shame for them and their parents”
In February 2017, the court heard she wrote: “I discovered my new least favourite demographic. Uppity r****ds.
“Some woman in a wheelchair came in then tried dragging me into a conversation about how my workplace is kitted out for able-bodied people only.
“And we should be ashamed.
“There’s literally disabled access. It’s just a different door.
“Then she was screaming about how on a plane to France they told her in an emergency she gets evacuated last because able-bodied people are ‘worth more’.
“No s**t b***h you have crab hands.
“Get back in the sea where you belong.”
The court also head she complained the woman was a “lesbian”.
She continued: “They’ve hired a downs girl [sic] at my work.
“Which is confusing. Because she’s got a higher up job than me basically.
“And yet she’s being babied by other staff members.
“So she’s on more pay, she’s down’s syndrome [sic], and she’s completely un-independent.
“Oy f**king vey, my life is a sham.
“I do genuinely feel bad for mentally-disabled people because they will never be normal and it’s a shame for them and their parents.
“But good grief. Keep them all in one place doing something.”
The trial, at Birmingham Crown Court, continues.
