They also think they're exceptional. They don't understand boundaries, and they don't understand that women have to deal with that shit from other guys who also think that, everywhere they go. Whether it be cat calls at the grocery store or advances at work.
I don't know Sacca or McClure, and from their writing and the way they project themselves, I don't think they seem like the type of people I care to spend time around, but it's pretty clear that this is a bad combination of arrogance and ignorance rather than malice. I had to stop reading Sacca's post after the 5th page of him talking about how great he is, but it sounds like he definitely had his Come To Jesus moment and is genuinely remorseful and working on not being an ass. That's a far better outcome than premature ostracization. Save that for the Bill Cosbys.
In order to make progress, I think it is important to recognize this distinction. There are no doubt some actual predators out there, but they need to be dealt with very differently than the dumbasses. I say that in part as a recovering dumbass myself, and as someone who faced accusations of malice and manipulation (in matters completely unrelated to women) when that was absolutely not the case. Hanlon's Razor and all.
