Earlier quoted context omitted.
I’m tired of people being denied basic and non-scarce resources because some people presuppose they’re yucky (even while making people yucky with those presuppositions). If we’re banning anyone from public services, I’d start with those who want to deny those services to people who most need them, in the way most likely to reinforce their biases by denying them access.
From my point of view, it's not about being "yucky", it's about ruining it for others. If a bathroom is provided, and you convert it to a state that it cannot reasonably be used by others, then you don't get to use the next one. If free food is provided for people and you come in and take it all to sell it elsewhere, then you don't get to partake anymore. There is no way to provide things in a way that people cannot…
This is, of course, only papering over the problem in the short run. Which is why the real solution must be to improve society.
Ostracizing people who behave badly will only make society worse.
