At my school, we are the only latino co-ed fraternity and there are 2 latino fraternities and 2 latina sororities. (as far as i remember) We sorta got along with the other latino orgs. We got along perfectly fine with the other non-latino greeks. but there was definitely tension with the latino orgs (mostly the sororities). we tried to be nice to everyone when we first started on campus but for some reason we couldn't play together.
My process was a blast. I pledged with a line of 7. 5 girls 2 guys and since we founded, we have grown to 24. My undergrad greek years were some of the best in my life and the fun doesnt end. I am still very active as an alum since my husband (also a member) is still in school so I still go to chapter meetings, rituals and all that good stuff.
