Many of Calvinism's most vocal critiques could learn a thing or seven from Gordan Runyan's latest post at Reformed Mafia (link). Gordon explains what TULIP:
T => Total Depravity = Really and truly dead in sin => R
U => Unconditional Election = Only cause of salvation to be found in God => O
L => Limited Atonement = Substitutionary and definite atonement => S
I => Irresistible Grace = Enlivening power of God on dead sinners => E
P => Perseverance of the Saints = Salvation is eternal life => S
(or ROSES, by another name)
is not. Frankly, given the number of misconceptions out there, this post is worth its weight in gold.
