I usually don't defend people on here - but I guess there's a first time for everything.
You can feed whatever the hell you want. Frozen, live, zombified, freshly killed, freshly frozen, bagged, tagged and t-bagged. If it works for you and your snake, so much the better.
However when Eric politely asked if there was any basis for the link you provided, you got defensive and down right cranky. You got real pissy with perhaps one of the few people on this forum who gives honest, thoughtful, helpful and generally balanced answers without any snark. Instead of packing up your toys and leaving in a huff, use this as an teachable moment. In any forum, some people will question the answers/advice you give.
If it's a personal preference - say so.
If you are doing something based on a belief - make sure that belief is rooted in fact.
Then be prepared to back up that basis.
I can pretty much guarantee you that anything that Mr. Alan recommends based on science, he can back up with corroborating data...
