@Master Knight DH, I see that you have effectively undone an edit that was made by a moderator in accordance with this wiki's Style Guide (specifically All The Tropes:Style Guide#Italics, Boldface, and Other Emphasis).
The discussion on the page's discussion page shows that the moderator in question gave you a short explanation, which did not include a link to the style guide. You called the explanation an ad hominem attack. (As an aside, please see Ad Hominem for a definition of what an ad hominem attack actually is.)
You are free to disagree with a mod. You are not free to ignore the wiki's Style Guide or any other rule that has been reached by consensus. If you want this rule (or any other rule) changed, please start a discussion on the wiki's Forum proposing the change. There is a link to the ATT Forums in the left-hand menu of every wiki page, under "Troping Utilities".
Since the moderator in question did not provide a link to the Style Guide in the explanation, I am going to treat this as a honest mistake. However, we have now pointed out the honest mistake, and "repeatedly making the same honest mistake after it's been pointed out" is grounds for a temporary block from editing on the wiki, according to All The Tropes:How We Do Bans Around Here. Please treat this as the warning required by that guideline.
