The most accurate response I can think of is many people on Lemmy want to be technically right (and I am no exception to this myself). You can see this in our many debates if the Democrats are a hindrance or the "best of the temporary solutions we have" in our debates in the best way to eventually form a working government.
The post in question (man vs bear) summarizes how much fear men have caused women throughout history in meme hyperbole fashion. Most people would "just get the point" that the meme is actually making. Women have suffered a lot from men. However, some of these Lemmy users correctly point out that its predatory behavior that should be called out; not "man vs woman". After all, anyone regardless of age, religion, sexual orientation, gender, etc. can be a predator. The meme is correct but those who oppose the meme are "technically correct" as well.
