Ad hominem is attacking a person's character.

Who's character to do you think I've attacked? Sky News is not a person.

Also I haven't dismissed them as a news source because of some random reason like I don't like their logo or the theme music they use.

I'm just sceptical of them because they've very, very recently been found to be spreading untruths related to this very issue.

So we'll just ignore the substance of this story because yt's algorithm labelled them for something else they spoke. That is very ... unwise, to put it politely.
