Open up Tinder on any day, and you'll be presented with a wide variety of women. There'll be normal college girls quoting 'The Office' in their bios, people explicitly looking for sugar daddies, older women in the workforce... the list goes on. Most of these women are decent to interact with.

But from my personal experience, the ladies that both Red Pillers and Female Dating Strategy would typically label as "low value women" (obese women, single mothers, trailer trash, etc.) are extremely passive-aggressive in how they present themselves, making themselves even less appealing than they would be without the rudeness. Instead of simply describing themselves or using corny jokes like most people on Tinder do, it's like they're attacking you or expressing frustration before you even swipe. These are the people who use lines like:

You could easily argue that these are just cherry-picked examples, but in all honesty, I have never seen attractive, not-tattooed, Ivy League women behave in this way.

Also, low value men don't act exactly like this - sure, they're rude and abrasive too, but they mostly channel their rage into weird, abstract biographies that say things like "fuck liberals" instead of focusing their bitterness into their own obvious flaws.
