Eat what you want and be happy
If you dont like or want to eat meat, dont. It is no simcha to eat something you dont like.
I was at someones house as a guest and they served me chopped liver and I hate chopped liver, IMO its one of the worst foods ever invented. I ate it because I didnt want to embarrass my host, but I will never serve it in my house. It was no simcha to eat it. I dont care for Chicken either. I hardly ever buy it. It is no simcha to eat chicken if you dont like it.
