I mean, come on, it's not that hard to see the overarching point here. Even pop culture portrays it this way (see Knocked Up, Trainwreck, etc.).
Let's stop expecting things and expressing them openly.
I'm sure the vast majority use it for hookups, but you can't generalize everyone.
The people I was responding to were saying "Women use Tinder for sex" (implying everyone), and "Everyone knows what Tinder is. It's a hookup app." (implying everyone)
My comment was to point out that you can't say things like this without implying that 100% of people feel this way, which is not the case.
Most men and women use Tinder for hooking up. It's my experience that even women that say they are interested in a "serious relationship" are actually quite interested in the opposite. Because there's probably some stigma associated with women simply enjoying casual sex.
