I think it is probably because the tone of the conversation was becoming harsh with the name calling,  ROV's are ok as far as I know. 
 
Does anyone know if I can bolt a stainless steel bolt to an aluminum flange?  Will the dissimilar metal situation cause excessive corrosion?  I want to use aluminum on one part because of the ease of machining but I don't think aluminum bolts would be strong enough.
