Well one “pile of shit” is racist, the other “pile of shit” is poor and works in manufacturing where they don’t want their hair ripped into a machine, and also likes punk music. Imo, to call the second ones piles of shit for simply being poor workers with haircuts that reflect work safety and like semi-heavy music (what skinheads actually came from that you’re sarcastically pretending to understand) makes you a classist (remember, know your shit, you aren’t racist but seems you’re classist) pile of shit. Also groups like SHARP exist.
Know your shit indeed, especially before being so confidently incorrect.
