While Calvinism taught in the true Biblical context can produce great fruit, extreme 5 point Calvinism produces fruits in its adherents that's like a mix of Noni fruit in the 1st image below, a.k.a. "vomit or puke fruit" since it smells & tastes like vomit & durian fruit in 2nd image which smells like rotten eggs & tastes like a mix of vanilla, garlic, onion, caramel & rotten cheese.
