There have been some interesting points and some single minded points in this thread. So my two cents worth might not even equal a penny.
It is part of the breeders position to have pride in the quality of animals raised (bull or heifer), especially if that animal is to be sold to another individual, does everyone take part in that? I would say "NO". Whether it is a small "weekender" or a "large scale" breeder, the thought is to make a quick buck for some. That mentality is seen in other businesses as well, a quick example is car lots, some good ones and some bad ones.
If you as a breeder take pride in your animals and the quality of your animals are good and proven then there is no reason Not to sell a "purebred" or a "mongrel" to any individual, as long as you are honest with that person and do not misrepresent that animal. The buyer is the one who is taking the Risk for their herd (being 2 cows or 200).
The biggest issue I have seen from individuals or sale barns is the misrepresentation of a bull just to raise the price. Example is when an auctioneer/ seller is promoting a cows bred back to a good black bull, your gonna get good black hided calves, good Angus background, when the bull might be a Balancer or Gelbvieh.
Culling bull calves is a must, some do not have the makings to be a good bull, herd sire or backyard hobby, that falls on the breeder/farmer to make that decision. Then he/she is providing the best animal to the buyers.
There are alot and if your in the commercial business then you have seen that as well, of people who do not know what a good bull is and will judge strictly by what is told to them by the seller, so again it is the responsibility of the seller to be honest, then let the buyer make the decision.
Purebred bulls on mixed cows, mixed bulls on purebred cows, or mixed bulls on mixed cows all are going to produce calves (some better than others in frame size, weight, and appearance) but bottom line they will still all sell at the end of the day so we can meet the market demands, high priced or low priced. Hopefully high priced since we do not see the price drop in the store but that is for another discussion. :bang:
