It’s probably hard to find an article these days that doesn’t mention one of those words (except maybe celebrity gossip). The world we live in.
I really don't need to know which party he is part of. If the article was about a party's stance, it makes sense - but the article is about one politician.
And ignoring that, it’s general context. Part of the job of a journalist.
Or to construct patterns that don't reflect reality.
Should we also list their ages, ethnicity, religious affiliation(s) in each article mentioning a Congressperson and construct those patterns as well?
Sorry, I'd like to think on my own.
When articles always mention party affiliation, people will judge the politician's behavior based on the affiliation, and not on his actions.
