Yes, I know. We live in the real world. My issue isn't people making judgements, etc. It's that I choose not to willingly expose myself to (and support) a system that enables those judgements to negatively affect me. Instead, I choose to spend my money with a system (a hotel) which does not allow the prejudices of individuals to get in my way.
Airbnb has chosen it's system (and refuses to address the flaws inherent in that system), so I've chosen not to use it.
