14 year old hasn't done his English work because "poetry is for girls"

My son's class is on their poetry unit and his teacher emailed me saying she can't get him to do any work and it's dropping his grade. I spoke to him about it and he told me "poetry is for girls." I think he's upset about multiple things. My oldest son is going hunting with my dad and the other boys this year and my 14 year old can't go because my dad doesn't know how to deal with his outburst. He was the victim of a crime back in August and he will have random outbursts when he gets overwhelmed but he was looking forward to going hunting because he thought he was finally old enough. And my 18 year old son is his safe person and he's leaving so I think he's just mad about a lot of things this month. I told him I know he's feeling a lot of feelings and feeling left out but he's got to do his school work and poetry can be fun. He just said once again "Mom. Poetry is for girls. I'd rather be hunting." So this is also about not being able to go hunting with my dad and the older boys. I emailed his teacher back apologizing and said I'll try to get him to do his work. I don't know how. He really thinks poetry is just for girls. Is there any ideas on how I can convince him otherwise or should I just pass this on to his therapist see if she can help? Any teachers on here with advice on how to get him interested?

@A I never said it was his therapist job to parent. Since she's been working with him on working through his trauma I thought maybe she could explain poetry from a different light since some people find it therapeutic.

@Melissa I do think to a certain extent he's struggling with his "masculinity" because we got some problems with him getting bullied at school because even though his face was blurred when some footage was released about the crime he was a victim of, some people found out. The bullying did stop but I do think this could have to do with him struggling with his own masculinity. It's why I wanted to get his therapist help because a lot of this is deeper than he just needs consequences. And my oldest is leaving for the hunting trip and he's really attached to his brother. I think he's just feeling a lot of feelings and it's spilling into his school.

@Mrs I'm not even sure what consequences I can give him. He doesn't really have friends to hang out with and only hangs out with my 18 year old. I had to take his phone because on our towns just busted Facebook page the man that victimized him was on there and some comment were victim blaming and he kept going through them so I took his social media away. He just sits at home and hangs out with his brother but my older son is leaving for the weekend so he doesn't really have anyone. I understand there needing to be consequences. He's just been really upset and I think what he's already going through is just spilling over in school
