There are two parts of this really and I think I'd be remissed if we gloss over one over the legit fear that women have.

First off: if you are a man (or masc presenting) and you aren't sensitive to the fact that women don't feel safe around men in general, then you are part of the problem. A lot of men in this category feel like they are "special" and "not that guy" and even though that may be true there is no way for women to know that without knowing you. So being considerate and honoring whatever boundaries women share with you goes a long way.

Being considerate also means having empathy for the fact that women feel unsafe around men. Take that into account in your approach with women. I always ask "Hey, do you mind if I sit here?" when there is a seat open next to a woman. If she says she minds, move on. Don't take it personally because it isn't about you. It's about her safety and her preference.

Second: I don't think women do men a kindness by saying that the bar is literally "be a decent human being". That might get a guy the first date or a conversation, but we all have compatibility personalities. I think a huge part of the problem of incel culture (which, let me be clear, is their problem and not women's!) is that it is self-fulfilling. Women saying to a specific man "hey, I don't think we're a good match" is fine but saying as a whole that all it takes is being "nice" is what gets incels into the whole "but I'm a nice guy™" narrative.

Yes, a guy needs to be a decent person. But the guy you want to date may need to have a beard or have a type B personality or be a good cook or use Arch Linux btw.
