I don't know the whole story if you've already posted it somewhere here so tell me if I'm wrong. (Also, I'm posting this from hm phone as can't really go back and forth between the reply screen and the image macro so if I'm not really on point with what happened let me know.)

I think the very fact that you're conscious of what might have been a mistake on your speaks volumes about your character. A consciousness and a concern with the feelings of other people is extremely important, because it shows that you have the very best intentions at heart, that you have the right idea. Whether or not you did something wrong, you didn't mean it.

That being said, it's perfectly possible that what you did made someone feel uncomfortable. This's quite unfortunate.

However, a person seriously concerned with an intersectional understanding of oppressions and other kinds of hardships would not respond with abuse of any kind, verbal or physical. They would make their concerns and feelings known in at least the hope that they would be met with understanding.

Now, with this being said, someone in a particular position where they feel so utterly victimised that they feel compelled to lash out doesn't necessarily put them in the right per se, but it remains a response that, for a person in their position, is at least understandable.

It's a really horrible thing to be in a situation where two folks so on edge that they might either express massive amounts of violence or break down completely have such fundamental misunderstandings and miscommunications.

Without trying to ascribe blame to anyone else, the most important thing right now is your well being. I really think that, whatever wrong you may or may not have done, you should try to seek help elsewhere and deal with this problem later, if indeed it's worth dealing with.

Getting better is more important right now; I don't imagine just telling you will work, but you should try not to worry about this right now, it's the least of your worries. Definitely don't feel as if you've done wrong, what's more likely is there's been an unfortunate misunderstanding.

I think that the line is drawn fairly distinctly for you simply because you've recognised what you've done here - not that you were right or that you were wrong, but that there's simply been an acknowledgement, and that is so incredibly important.

I think that alone means that you should not have been treated the way you were and that you deserve an environment in which you don't have to risk that kind of treatment, and at the same time that the person involved might have rightly felt valid in their behaviour. It's a difficult matter to deal with because different things are right for different people, but that doesn't mean that you don't deserve to be treated right.

Seek help elsewhere, and if you feel so inclined try to seek contact with the group you attended so you can try to explain yourself to the person who felt they were wronged by you. That's my advice at this stage. And all the very best of luck - from what I've seen so far, you seem like a decent, sensitive person who deserves good things in their life. Take care!
