I'm know I'm not alone here (Merlin for example) but I grow orchids for a living guys! I have almost 8 hectares of them, well over half a million plants.
Having said that I'm too far out of the way to get involved in any of the International groups and despite the fact that we are Bali's ONLY orchid garden and far and away the largest grower of orchids on the island I have so far managed to politely evade the Bali Orchid Society. This is going to end in tears pretty soon though cause the president is a good friend of mine and he's beginning to realise that I am forever busy when it comes to arranging meetings to discuss my becoming involved. He he...
Anyway, my take on why there is so much more politics in orchids, and there is actually plenty in CP's too if you know the right (wrong?) people, is simply that for every CP nut there must be about 1,000 orchidophiles. There are many many more people into orchids so it follows that there are more personalities to clash, the market is much bigger ergo more money at stake, etc, etc.
Secondly, like it or not CP's are a tad niche and without sounding snobby, I think CP's appeal to a more intellectual crowd. Orchids are (often) big and bright and anyone without a clue about plants can go "oooh, look at that pretty flower".
Cp's could be considered ugly by those that don't appreciate them - I was in a meeting with a Japanese artwork company the other day, 3 ladies, and the conversation somehow turned to Nepenthes (don't ask!). They were horrified when I told them I had named a Nep after my wife as they thought it was ugly. Point is that I think not everyone can appreciate CP's and the people that do are more inclined to think about their hobby than just grow them cause they look good for a month. Those same people are therefore willing to think about other aspects of the hobby such as conservation and the ultimate good of the plants rather than letting politics get in the way.
