Yes, we are a part of the exotic pet trade. At least, any time we buy or sell, we are. Not sure just keeping them counts, but buying supplies probably does.
As far as the stuff discouraging exotic animals in captivity.... well, honestly, you could probably find something discouraging pretty much anything if you looked around the internet long enough. But, yes, there are groups that are strongly against the exotic pet trade. Animals rights activist wackos mostly.
What you should be worrying about, IMO, is not that some people disapprove about the exotic pet trade, but the fact that those groups of people, along with the sensationalist media, are succeeding in getting laws passed that are making it illegal to own some of these exotic animals. Try reading the list of animals that is proposed to become illegal in West Virginia. The bill has already passed and been signed into law. The only issue now is exactly what species will or won't end up on the final list. Or perhaps it has been finalized. I'm not totally on top of it. But here is a link if you want to read more:
