Personally, I do like them.
We have blood parrot cichlids and they are among our favorite fish. We will soon be getting a short body flowerhorn, too, for a solitary tank.
I don't think there's anything wrong with hybrids as long as people know what they are getting (vs. thinking they've bought a pure fish and then being disappointed later). Our parrots have no trouble living the life they were made to live -- life in an aquarium. They eat easily, swim very well (better than any tetra ever has!), and have the most pet like personalities. If we didn't own these fish, I'd never have realized how smart and people oriented fish could be. They are unlike any of the other fish we keep and we adore them.
One of my hobbies is breeding horses and it's something I've put lots of years and time into. I am so aware of good conformation and breeding only the best of the best (not just the best of what you can aquire). I feel function follows form. Just very aware of what should be considered when breeding an animal and the ones I breed may be in this world for 30 or so years. My perspective is that the blood parrot fish, while "funny looking" to some, do not have any handicaps that prevent them from living good quality lives and serving their intended purpose (to bring happiness to their owners).
