I've seen way too many "fathers" make statements like that. Sure the man would wish that his son would follow in his footsteps but it doesnt always work out.
I've heard the same statement about football, baseball etc. If we lived a world where each man had to kill his own food the son would either harvest deer or perish. However, just to blatantly say that "no son of mine will do (or not do) something is setting yourself up for dissapointment.
My kids go hunting with me because I make it fun for them and they enjoy it. I didn't force them into it. They saw my example and wanted to follow. It would be wrong of me to try to force them into it.
