Even when faced with being inarguably and factually wrong, you stick to your narcissistic teddy bear that you're right, and even link to "proof."
From your link, "The most common question people ask about quotation marks is whether periods and commas go inside or outside, and the answer depends on where your audience lives because in American English we always put periods and commas inside quotation marks,"
You've lost this one, badly. Better to concede you're wrong than keep up the charade. I continue to challenge you to find an American source to support your usage, and let's try to remain credible instead of sites like that one you linked to even though it also proved you wrong.
