I posted this in another thread for this meme:

Fun meme and all, but I somehow doubt the author has much experience working with children. Some kids are genuinely little terrors, in that everybody around them tends to have a bad time in their presence (adults, peers, and usually, the kid themselves). "We live in a society" and all that, so not being able to function within that society (especially as a minor since they don't even have the option of living off-grid in the woods as a hermit) is, sorry to say, a problem.

This is also a gross misrepresentation of ODD as defined by the DSM; here's a snippet of the diagnostic requirements (emphasis mine):

A pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness lasting at least 6 months as evidenced by at least four symptoms of the following categories, and exhibited during interaction with at least one individual who is not a sibling:

Angry/Irritable Mood

1. Often loses temper
2. Is often touchy or easily annoyed
3. Is often angry and resentful

Argumentative/Defiant Behavior

4. Often argues with authority figures or, for children and adolescents, with adults
5. Often actively defies or refuses to comply with requests from authority figures or with rules
6. Often deliberately annoys others
7. Often blames others for his or her mistakes or misbehavior

Vindictiveness

8. Has been spiteful or vindictive at least twice within the past 6 months

There's also additional qualifiers such as for frequency (they're not pathologizing having a bad day or two).

So no, your "eat the rich" and "ACAB" laptop stickers are not going to get you slapped with an ODD diagnosis.
