He's only a simp to dudes who don't understand what a simp is. He's more like a "happy wife, happy life" type of dude but because he's Black, rich and athletic, cats just don't understand why he chose that life over being a player or acting like an Alpha male while married. His brand of religious beliefs seem to influence him a lot.
Women still find him attractive and view him as a catch so I don't see him as a classic simp. Just a husband who places a lot of value on how happy his woman is even if it makes him look silly. Dudes with game wouldn't move like him but hey not every man got it in them.
It's funny because Future and a lot of other rappers are big time tricks and simps but they are considered cool and gangsta to a lot of dudes who like their music. Nothing player about the way Future moves imo. Ditzy broads are easy to bag when you're rich and party all year long.
