This is my first ever forum post and I'm not great at expressing situations so forgive me if it sounds like i'm being dramatic!
So i have this online friend, lets call him Brad, who goes to one of my irl friend's schools. I've known him for about a year and recently he created an instagram groupchat with two of my school friends and I. Last night he asked a pretty random question, "Is anyone here a furry?". Now I myself am not a furry nor do I have anything against them, but I was well aware of how he felt towards them. My other two friends responded no as well and one of them asked "why?". Brad responds with "they are a mistake in our society, a plague". This is where the argument kicked off and he got a lot more violent from this point on. He continued to express why he hates them (which consisted of mostly extreme exaggerations and 'facts' that had no statistics). My friend and I provided points to try and get him to reconsider his view and stop being so aggressive, he constantly ignored them by saying 'they made no sense' (he's done this in multiple other arguments in the past as well) and sent multiple anti-furry memes (pretty harsh ones, at that) despite the subject of our conversation. His arguments were extremely violent and were making everyone uncomfortable. He admitted that his views were extremely harmful but claimed it didn't matter because it was "his opinion". I understand people are entitled to their opinion, but only when they can actually argue for it, which he definitely couldn't. The conversation quickly moved from that topic and went to the subject of accepting that not everyone has the same interests, but he quickly assumed the same closed-minded opinions that he had before.
He acts like he's all noble because they're 'his views' and he 'stands for them'. He said he wouldn't change them, and I see this as willingly being stubborn and closed-minded. We never insulted him, but he insulted us. Brad later left the server and blocked both me and my friends.
Despite blocking me, he went to discord this morning and sent me a whole paragraph, yet again insulting me, swearing at me, and comparing me to his ex gf and her friends. He ended up blaming the argument on me for 'finally figuring out that he was a negative person'. I responded to him, he said ok and blocked me.
I've been thinking and now i'm wondering if i'm actually in the wrong??
