My philosophy, in general, on big parenting issues is: "Ya gotta do what works for you and your child." I do oppose methods that are neglectful or harmful. And, to be honest, I have a low threshold for anyone who avoids encouraging a child's development because it's hard (getting them to give up that bottle or stop hitting can be very, very, VERY difficult, but in the long run they need our help to move on).
Acknowledging, then, that there area a wide range of effective approaches to potty training, the best advice I can offer is that you need to investigate different methods to find the right technique for your family. I know kids who took to the potty in two weeks and others who had to drop out of preschool because they just refused to use the toilet. Try not to let anyone pressure you into starting too soon or using techniques that aren't appropriate for your family or child.
It's also important to be honest with yourself and be sure that you don't make potty training more difficult for your toddler by injecting into the situation your own feelings (including the totally understandable desire to never again touch a poopy diaper).
You need to be there to support and teach your child, but by the toddler years, you know he already has a will and opinion all his own. So be patient, work together, and, as my friend once told me during an especially exhausting day, your child should certainly be out of diapers by college.
