If you force him to read he will just learn to hate reading.

And if he is in a public school then you shouldn't expect him to be encouraged to read in kindergarten, more likely he will be encouraged to dumb himself down to the dumbest kid in the class... at least that is the way public schools are in my area.

Your best option if he is in a public school is to explain that school is for being around others his age and the teach him at home.
