Agreed. OP should be working on critical thinking skills in general and not specifically focusing on logical fallacies.
Logical fallacies and argumentation theory in general certainly have their place. But unless you’re taking part in a debate club or otherwise getting really really deep into these topics, they may do you more harm than good in thinking critically and having productive discussions.
The reddit (and, previously, slashdot) obsession with logical fallacies has been almost entirely as a way to prevent critical thinking and end discussion rather than promoting either.
