So many people with strong as fuck, ongoing, developing opinions about how theme parties aren't racist who also never post in any racial justice topics. This is who we are, America.
It's an important discussion, whether you believe it or not. It's not about determining whether the people at the party are racist (that can be accomplished easily enough by observing their words and actions). It's about the topic of "Is it intrinsically racist to borrow from or mimic another culture?"
The answer should always be No.
Language, culture and religion should not be protected above human rights. And like it or not, people should be afforded the opportunity to use cultural artifacts and ideas at their own discretion. Of course the down side is that people can use it for negative or hurtful reasoning, but your feelings do not take precedence over another persons right to express themselves verbally or artistically. If you can't take a hard line with this, then you just end up with a bullshit hierarchical value system of what is and is not culturally acceptable.
And just because I know it will come up; language, culture and religion do not entail genetic qualities such as skin color, gender, sexual orientation, physical traits, and so forth.
And as for you, I don't know you too well, but every thread I've ever seen you in, you're just playing the "I'm the good guy" short game. Just recently in the BLM/Pride Toronto thread, the first thing you did was come in and lambast all Canadians for nitpicking BLM's demands, even though the only demand being criticized was the one that was damaging to the LGBT community, and dare I say homophobic. But there's no time to read the details, BLM>Pride so I've got to get my shots in!
The reason why I don't show up in many racial justice topics is because I have little to add to the discussion, other than "This is horrible." I show up in threads about homophobia and injustice at the hands of religion because it's something I can relate to. In my eyes cultural protection is no different from religious protection, and it is something I strongly oppose.
