> I cuss a lot at work. But I don't cuss at people. I have a coworker that says things like "It's fucking ridiculous that X task isn't done" to the people who are doing that task. This dude is toxic to be around.

This example has nothing to do with swearing, which is just adding emphasis. The sentiment being expressed in the first place is toxic.

Compare: "it's absolutely absurd that this isn't done" and "it's fucking awesome that this got done so fast".

Quite obviously, the latter isn't the toxic one.
