It's not against the rules, but trolling and being a nuisance is so you can't just start screaming racial abuse at people just to try rile them up. It's probably an ad hominem most of the time and likely off-topic in most threads anyway. Abusing people based on their race tells me a lot about them though and these people usually aren't worth your time and if this sort of thing offends someone they should just utilise the ignore button and problem solved. This whole cancel culture trying to silence anyone who says something they don't like is getting out of hand and it's a very slippery slope (hope I just didn't offend Vietnamese now:
https://www.urbandictionary.com/define.php?term=slope).
Most people here are pseudononymous, if people know you're of a race, you've probably told them (and potentially too much).
I think most of the abuse here is generated towards groups or nationalities with derogatory terms like pajeet etc and most forum member's nationality probably isn't a secret most of the time.
I could get onto another argument about my annoyance only black people are considered slaves by the masses. It completely invalidates most of Europe taking other Europeans as slaves.
I wouldn't waste any time worrying or arguing with these idiots. It is quite worrying though how they've started redefining words and language to suit their beliefs. It's seemingly become quite a generally accepted term amongst them now that only white people can be racist, which is obviously completely moronic but suits their identity politics and victim mentality. Slavery is as old as mankind and Africans were enslaving themselves and then Arabs long before the Europeans got there, but nobody wants to hear about that or all the attempted genocides that happened within Africa:
https://en.wikipedia.org/wiki/Genocides_in_central_AfricaI think most of us can generally accept that racism is bad and slavery was horrific, but unless you're out marching in the streets screaming Black Lives Matter some people will still call you racist, but you have to remember that these are the sorts of hypocritical idiots you're dealing with:

I don't see anywhere in the rules where racism is even mentioned meaning it's not a big deal in bitcointalk. I prefer looking at a case where someone could call me names like "Pajeet, Habibi, curry muncher, white trash etc" just similar to one trying to say am stupid, foolish, asshole etc
It's just a stranger who doesn't know me trying to describe who I am. Why would I be offended if a stranger tried to abuse me?

If someone uses terms like this is says a lot about them more than anything else. I mean, if you're going to be racist at least come up with something witty or original.
That being said: I love that it's allowed to say (almost) anything you want on Bitcointalk. It's up to each user how they handle that freedom.
You have super thick skin, so you never get mad when people say you are a dirty bot, but some people may consider racist calling someone a bot.
And don't even get me started about gender topic, and the fact that we have two genders in forum profile settings, but maybe people will ask to add all other 6538 invented new age genders.
No rules are needed for anything like this in Bitcointalk.
Woah there, you don't want to get negative feedback from gaylord2067 for being
transphobic homophobic.
