Just how ruined is Thanksgiving?

How could such a question possibly be answered?  What units of measurement would even be used?  TiR has no idea.

However, perhaps the question could be indirectly answered.

So, as part of TiR's annual ruthless interrogation of its namesake proposition, here is a list of a dozen items alleged by the internet"s" to be "ruined beyond measure":

England, or so thought the French in 1386

Korea's ceramic industry, in 1592

the physical culture movement's "iron game," during the 1930s

Darjeeling, by tourism

the career of Dr. Anna Pau

art, "unless someone has the sense to bring back the magic like Picasso"

the Harry / Ginny romance, in Harry Potter and the Deathly Hallows

Damon, in season 4 of "The Vampire Diaries"

Lily's life, in The Flower and the Sword Harlequin romance

most power supplies, after the Dark Axis ran amok, in this Superior Defender Gundam Force fanfiction

the ordinary man in Nigeria, by inflation, mainly due to increases in the Naira cost of imports

the cocaine user, when the powder hits his nose

Is Thanksgiving at least as ruined as any of the above?

If "yes," than the ultimate answer is obvious.
