<human>: Can you provide a brief overview of the text?

My good friend recently got a sex change from a man into a woman, and is now transgender. 

Last night my boyfriend, my friends and I were over at my place and my friend who had the sex change was speaking about just gender's in general. 

One of my friends said to Max (boyfriend) is cisgender. Max replied "what?" they were trying to explain to him it just meant he was happy with the gender he was born with without alienating transgender people. 

My boyfriend max had like this breakdown, it was like something inside of him just snapped I have never seen him look so angry. 

He got up and he was saying " I am a fucking male, not cisgender, not alien gender, not dog gender or what ever else you want to make up but a human male" he went on a tirade of how he is sick of putting up with this shit just to not try an offend someone. 

He turned to my friend and went off about how there is no in-between, "pick a fucking gender or are you going to try and Identify as a fucking flamingo soon as well" an exact quote out of his mouth 

He stormed out, I tried to stop him and clam him down but he was having none of it. He went off at me about how pissed off he was that I now have to be called something else than what he is to not offend somebody. 

He said he wanted to be left alone, I want to call him and sort this out. But my friends are telling me I can't be with someone who is intolerant of other people 

I just need an outside opinion on this
