Here are several links which either say the punctuation-inside-quotation-marks always rule, or even specifically bring up titles and STILL show the punctuation inside the quotation marks.

2.  Titles  Use double quotation marks to enclose the titles of songs, short stories, essays, poems, and articles:

Softly, almost tenderly, Legree recited the lyrics to the song '''"She Made Toothpicks out of the Timber of My Heart." '''[This is a title]

The rules set forth in this section are customary in the United States. Great Britain and other countries in the Commonwealth of Nations are governed by quite different conventions. Nowhere is this more apparent than in Rule 3a in this section, a rule that has the advantage of being far simpler than Britain's and the disadvantage of being far less logical.

Rule 3a. Periods and commas always go inside quotation marks.

Punctuation inside or outside final quotation mark?

Note that in US English, the full stop usually goes inside the quotation marks in all cases:

He said: "I love you."

She has read "'''War and Peace." '''[This is a title]

From AP Style: Periods always go inside quotation marks. –p 361

From MLA Stye:  Periods and commas precede closing quotation marks, whether double or single. This is a traditional style, in use well before the first edition of this manual (1906) –Section 6:8

The CMS goes on to describe exceptions for textual studies and British usage, but for practical purposes, writers of American English can go with the “ALWAYS put a period INSIDE the quotes” mantra.

I'm fired up because of your "please don't try to prove me wrong again" statement. I found dozens of sources which directly refute your claim - some of which even say Britain does it your way, America does it this way. Your one source does not say what country's rules it is following.
