Most, but not all. There's a subdivision of humans called punk rockers whose fashion choices and lifestyles include them styling their hair and wearing clothes in non-conformist ways. Sometimes it's not even that dramatic, but I think you get the picture. Tumbleweed is pretty conservative, but there's also a college here, and college students are known for experimenting and rebelling against authority, so who knows? They may assume you're doing something like that.
Generally, killing isn't appreciated, so yeah. Avoid that.
