Racism, xenophobia, dishonesty, arrogance, pretentiousness, ableism, spreading rumours / untruths, violence, cheating / unfaithfulness, assuming without lived experience.
I grew up with cultural diversity, since my mother's friends were from many different nations, and am glad I did. Xenophobia doesn't necessarily mean racism, but hating on cultural differences. For example, being half Dutch, sometimes for fun, I've said some Dutch words when talking with friends. In a predominantly white, small, parochial country town, I've had some wanker come up to me and say, 'You're in Australia now. Speak English!' I then go back to my regular Aussie voice and respond with, 'Is that right?'. The wanker then looks confused and angry. My friends were interested to know some Dutch words. Or, the open mouthed, angry stares I get if I speak English with a Dutch accent, because the shire I live in isn't used to cultural diversity. Thankfully, that shitty behaviour isn't everywhere.
Since I have a degenerative, genetic disability, I've become more aware of ableism. I use a rollator-walker when I go shopping and some people talk down to me like I'm 5 years old. It's for my legs because they get tired and achy without it. It doesn't power my thought processes. Sometimes, if I'm with a friend, others will talk to my friend about me, in front of me, because they think I can't answer for myself. Also, since my disability has become more obvious, men (apart from the fkn stalker whom I'll never want a relationship with) don't ask me out as much. A bit of metal with plastic handles seems to scare them off. Meanwhile, they drive a car with more metal and plastic. When I'm asked out, it's usually after they realise that I do have a personality and am human. Eventually, disability happens to all of us; for most it's not until they become elderly. They won't realise how hateful they've been until it happens to them.
In small, parochial country towns, they have nothing better to do than make up stories about other people and spread them. The fictitious version of me has a much wilder life than I do. I refuse to join in with the rumour mill so I'm on the outer. I think it's a shitty thing to make up nasty stories about people.
