oooooh the little snakes figure that of course there powerful after all we keep it in the family and anybody with any brains of course has to know that if you marry your sister and or cousin who share the same blood as you then of course you have to get more powerful and the idiots that think if you actually lower yourself and actually touch a mudblood let alone have sex with one...shudders! How can those moronic cretins actually believe that bringing in mudblood (new) blood will renew and make our blood stronger, how much of an idiot do they think we are!
