help the guy in learning latin
The Latin thing again... 
It is nothing prejudiced against latin. It is blatant ignorance. Stupidity doesn't even feature. It is mere unwillingness.
I can tolerate someone intellectually challenged, willing to learn, showing enthusiasm. The blatant disregard for procedure, and unwillingness is what gets to most of us. The reason scientific names are used, as Stan pointed out, is so we as South African keepers, can converse with people across the language barrier and both parties know what the other speaks off. I am going to go as far, to say, that the impression I get from these people, and I am sure many can name a few on our forum too, that sells tarantulas, but refuses to use the scientific names, do so with utmost intend to mislead.
As result I will by no means do business with such people. I will engage them with utmost fervour on any and every thread I find where the scientific names are not mentioned, and I urge others to do the same. I am not saying stomp the first newbie that doesn't bear knowledge of the method, but educate them, and should they fail then to comply - engage.
