Can I not defend myself in chat?

Hey guys, I was just given a 14 day ban. Not looking for sympathy but I am looking to understand. I was flamed by a player and I defended myself. His duo went in on me and was harassing me as well so I went off in the chat. I forgot to report them after and I got banned immediately probably for dropping a few curse words. Is there no consideration for who "threw the first punch," so to speak in these matters? Are good people going to keep getting banned because we won't let someone push us around? I don't know obviously I'm not a saint but I just wanted to reach out to the community because I know I am not alone in feeling this way.
