This categorically isn't defunding police, this is police abolition, and getting them confused is likely why you think it's a luxury belief because I fail to see what's luxurious about getting tear gassed every Friday/Saturday night or having the cops stand aside letting groups like the Proud Boys brutalize protestors and journalists. There's nothing luxurious about getting tear gassed for 3 months straight, it's a genuine struggle.
What's luxurious is you and I.
