There are so many benign reasons you can reject someone.
Maybe you just deleted the app because you’re done with trying for now.
Maybe you like someone but move on because things just got serious someone else you found first.
Maybe you like someone but there’s some dealbreaker like distance or having kids or something else random they have a bias about.
Maybe you reject someone without thinking there’s anything wrong with them, you just don’t feel compatible.
And yeah some people will reject you because you’re not rich or your looks aren’t perfect, that happens too, but only a small percentage of people are rich or look perfect, you just have to make peace with not being that. Just about everyone else is in the same boat.
Don’t let incel types cause you to shape your impression of why you’re being rejected and turn it into a reason to hate a whole gender. Some of them have shitty standards, sure, but don’t turn it into a rule about them. That leads to a downward spiral.
