The distinction is short term vs long term, that has nothing to do with xenophobia. AirBnB reduces the price of short term stays (six months is short term - long term rental contracts typically start at 1 year), but has a significant negative effect on people that stay in the city long term. AirBnB converts homes intended for long term residents and repurposes them as housing for short term stays. This significantly reduces the supply of houses in a market that already has a low supply, causing an immense spike of housing cost for those staying in the city long term. The fact that something else exists that also contributes to this problem does not take away the immense negative effects that AirBnB has, that's just whataboutism.
