Seems to get irritable when I don't agree with his narrative

Been seeing a therapist (psychoanalytic) in order to be assessed to get onto group therapy, he's been making narratives about how he thinks my behaviour patterns present, many of them are useful but often not based on much information. All well and good there's a dialectic between my truth and his as expected but last session i drew a line and told him no I disagreed with his narrative and he seemed to react pretty badly...

I said I got too emotionally involved with people doing bad things in my view and getting too into the situation often to social detriment, he said it's more of a rant and I said no I have to draw a line here I'm not grandstanding or giving a speech in the agora, I know because I have done things to my own detriment to stand against things I feel aren't right.

Long winded but should I count this as a red flag? I am tired of gaslighters and there may be transference going on here but surely he's not meant to tell me what I am categorically...

What makes you think he reacted badly? It sounds like he disagreed with you and you have blown it out of proportion:

Nobody actually ever tells anyone anything about themselves categorically, that's simply a perception of the other persons words. He tells you what he thinks, that's what you pay him for. He could remain silent every time he disagrees or he could just agree with you but that would be inappropriate given that you are paying him for his thoughts. If you are thinking that he is tells you things and you think that he is telling them to you categorically, that's definitely transference and you should bring it up. You both might disagree with each other a bit more but hopefully you will eventually come to some point of resolution.

Having been in psychoanalysis for a few years I am inclined to agree that sometimes it feels like gas lighting. I think though that the more you work through it, the more that it's possible to see that when you react to something the therapist says, it's because of something in you. When I feel like my therapist is reacting badly to me, it usually signals a red flag to me that I have some conflicted thoughts about stuff that aren't resolved, otherwise I'd either agree with him or I'd feel totally fine and unaffected by him expressing an opinion that I disagreed with.
