ANSI Y14.5 2.5 SINGLE LIMITS ?
(OP)
Dimensioning a forging with a size dimension ie: "6.0 MIN".
Per 2.5 I interpret the size limit to be 6.0 to infinity.
There are others that say the drawing tolerance block dictates the maximum size tolerance with the dimension decimal places.

You are correct, your colleagues are at best ignorant.
ASME Y14.5M-1994 section 2.5 Single Limits
...Single limits are used where the intent will be clear, and the unspecified limit can be zero or approach infinity and will not result in a condition detrimental to the design.
(Sorry, I'm in a bit of a bad mood today and my gladly suffering fools threshold is a little low.)

In this case the intent is clear, but either zero or infinity are not acceptable
