😒 Mobility -
Repeats preconceived ideas about motion or movement skills

 An illustration of Witty shows the phrase 'The first documented DoS-style attack in February 2000 crippled [hobbled] Internet commerce.’ The words in brackets are shown as alternatives.

Outdated, hidden or even discriminatory wording pigeonholing people with a mobility impairment. 

What can you do?

Ask yourself "What would I write if this person was in full capacity of all their limbs?"
