Homophobic is the adjective, and homophobia is the noun. So when he said “Do I look like a homophobia?” The English is correct.

(If someone is homophobic, they’re a homophobia.)

And whether or not he is homophobic is… unknown. Seems suggested by that particular character but I don’t think so.

nahh if they r homophobic, the agreed noun is a homophobe

nahh if they r homophobic, the agreed noun is a homophobe, homophobia is the noun for the disease while a homophobe is someone who has the disease

I don’t think it’s a disease per se rather an irrational fear. But yes, you’re right about everything else. Thank you for correcting me.
