Glad to see we agree- I wasn't trying to suggest that you were in favour of hybrids...
I see no problem either in breeding the best looking to the best looking- such selective breeding has happened for ages and goes on all the time in nature (not always for the best looking though). Personally, I don't have any problems with line breeding to speed up the creation of morphs, etc., as long as people realize the potential downsides to such breeding projects in terms of overall animal health and fitness.
I can even live with people intentionally producing naturally occurring intergrades, though I have no interest in this (or line breeding). Personally I tend to think that the natural forms are the prettiest, but that's just my opinion.
The only thing I disagree with is hybridization between species when such hybrids are fertile. If they were infertile, I wouldn't care.
