Is this a reasonable request or naw?

Only vegan in the family & the family groupchat often has members sharing pics of their meals, pics of chopped up animal corpses...

Would you reword this or anything?

"I'm getting a new phone number. Please do not add me to any groupchat. Just txt me directly if something is important for me to see. Either that or label the groupchat 'No Pics of Dead Animals' as I am not wanting to open up txt msgs to see pics of dead animals. Either route is fine with me, but please respect my request. Thank you."

Or should I just leave it at this?

"I'm getting a new phone number. Please do not add me to any groupchat. Just txt me directly if something is important for me to see. Thank you."

Eh?
