"Bluish yellow? You mean 'green'?"
"Oh, I don't like labels."
Labels exist for good reason. They can help people communicate when used correctly. They can also prevent communication when used incorrectly. If you call green "blue" your message is getting muddled.
If you call a conservative or a socialist "libertarian" you are not communicating, you are confusing. Yet major "news" sources are doing this all the time. So much, in fact, that it is probably intentional.
Be annoying. Correct them relentlessly.
