Many Type 2's have to take insulin to control their diabetes, it does not make them Type 1.
Type 1 is an autoimmune disease where the pancreas has been compromised in some way. Type 2 is generally where you have built up a resistance to insulin in some way and therefore cannot process glucose properly.
A type two can control their diabetes by different methods and also may still be producing their own natural insulin.
A Type 1, after an initial 'Honeymoon period' does not produce their own insulin or very, very little and must rely on injected insulin for the rest of their life.
