A couple of things to note:
1) We can defeat HSUS through education. If more people realized what they truly are, they will stop sending them money and that will be the end of them.
2) The complete document for the rule is on kingsnake.com. I read quite a bit of it and it's pretty clear why the boa constrictor isn't listed. It's because it represents too much money. There was a part in there that hinted of this.

So from the blog posted here, we had this thing almost defeated. Due to the efforts of HSUS, the powers that be ended up doing what they probably felt was a compromise. The way I see it, there are two things we can do that will effect future outcomes more than any and that is to educate enough people on HSUS to hit them in their pocketbooks from lost donations (Facebook is a very powerful tool for this) and we all need to be voting and educate yourself on what a candidate's track record is when it comes to supporting small businesses. As far as undoing the damage that is already done, it's going to be difficult. I'm not sure if we will be successful until the politicians responsible for this are removed from office. Thankfully, we have that opportunity later this year.
