I cannot overstate how toxic to your relationships and to yourself this behavior is. You need to let people express themselves, and listen when they do. That's about as close to a "prime directive" I can think of right now, when it comes to human interaction.
No one is saying that they are making assumptions for others or not allowing them to express themselves. But if you deny that you are prejudiced, you're going to end up imposing your own will on others because you continue to suffer from your predisposition without being cognizant of how that affects them.
If you want to talk about groups of people doing things other than this, why did you create two new accounts to reply to me?
I believe you're one of the people I'm talking about, and I don't think you're taking it very well to find out some folks think of you as arrogant.
I'm not surprised you find that, "pretty toxic, tbh", but I stand by what I said. You're not the first "empathetic" person I've talked to who gets unreasonably upset at the notion that their perceived good trait is actually a negative trait.
People often decide how to feel, and we need to let them.
I'm all for letting people figure out how they feel about things, but sometimes we don't have the luxury of time and we need to interpret in the moment. This will happen no matter what as long as we have a biological form, and pretending otherwise serves no one.
The perceived thoughts and feelings of others, and that's critical. You don't know the minds of the people around you, and presuming some kind of negative experience on the part of others is not often accurate.
The problem with empathy would be if you presume everyone to be having a bad time when it seems like, to you, they should be having a bad time.
IMO, that's actually arrogant, to think you can accurately know what someone else is thinking and feeling. Perhaps part of your struggle is this unidentified arrogance that you know the minds of others.
