I mentioned a country that is known for modern-day slavery
You went off on a wild tangent about slavery when they were making a point about python conference organizers.
Just because someone says the word 'slavery' while emphasizing their point doesn't mean it makes sense to unload some unrelated slavery facts.
This is like someone reading a wikipedia article and clicking on a single word, then going to the wikipedia page that has no relation to the original article. (Please don't respond with a history of wikipedia, that isn't the point here)
