A forum would be entirely boring if everyone shared the same opinions. That said, it seems like you've already pinpointed the problem in your posts. You just have to work on that delivery a bit because we're ALL mere mortals here.
As live is an acceptable option for folks in the states it's going to remain a viable suggestion for getting people's snakes to feed. I think you would make a valuable asset for offering advice on getting those snakes to take f/t if you can do it without belittling others while pushing your agenda. It sounds like it was unintentional though so maybe just work on not getting so defensive. If a lot of folks are getting heated about something you say maybe it's a clue for you to go back and reread it a couple times.
